## Class DefaultGroovyMethods

- java.lang.Object
- - org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport
  - - org.codehaus.groovy.runtime.DefaultGroovyMethods

-     public class DefaultGroovyMethods
      extends DefaultGroovyMethodsSupport

  This class defines new groovy methods which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. `public static String reverse(String self)` provides a `reverse()` method for `String`.

  NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

    - #### is

          public static boolean is(java.lang.Object self,
                                   java.lang.Object other)

      Identity check. Since == is overridden in Groovy with the meaning of equality we need some fallback to check for object identity. Invoke using the 'is' method, like so: `def same = this.is(that)`
      Parameters:
        `self` - an object
        `other` - an object to compare identity with
      Returns:
        true if self and other are both references to the same instance, false otherwise
      Since:
        1.0

    - #### identity

          public static <T,U> T identity(U self,
                                         @DelegatesTo(value=DelegatesTo.Target.class,target="self",strategy=1)
                                         Closure<T> closure)

      Allows the closure to be called for the object reference self. Synonym for 'with()'.
      Parameters:
        `self` - the object to have a closure act upon
        `closure` - the closure to call on the object
      Returns:
        result of calling the closure
      Since:
        1.0
      See Also:
        `with(Object, Closure)`

    - #### with

          public static <T,U> T with(U self,
                                     @DelegatesTo(value=DelegatesTo.Target.class,target="self",strategy=1)
                                     Closure<T> closure)

      Allows the closure to be called for the object reference self.

      Any method invoked inside the closure will first be invoked on the self reference. For instance, the following method calls to the append() method are invoked on the StringBuilder instance:

           def b = new StringBuilder().with {
             append('foo')
             append('bar')
             return it
           }
           assert b.toString() == 'foobar'

      This is commonly used to simplify object creation, such as this example:

           def p = new Person().with {
             firstName = 'John'
             lastName = 'Doe'
             return it
           }

      The other typical usage, uses the self object while creating some value:

           def fullName = person.with{ "$firstName $lastName" }

      Parameters:
        `self` - the object to have a closure act upon
        `closure` - the closure to call on the object
      Returns:
        result of calling the closure
      Since:
        1.5.0
      See Also:
        `with(Object, boolean, Closure)`, `tap(Object, Closure)`

          public static <T,U extends T,V extends T> T with(U self,
                                                           boolean returning,
                                                           @DelegatesTo(value=DelegatesTo.Target.class,target="self",strategy=1)
                                                           Closure<T> closure)

      Allows the closure to be called for the object reference self.

      Any method invoked inside the closure will first be invoked on the self reference. For example, the following method calls to the append() method are invoked on the StringBuilder instance and then, because 'returning' is true, the self instance is returned:

           def b = new StringBuilder().with(true) {
             append('foo')
             append('bar')
           }
           assert b.toString() == 'foobar'

      The returning parameter is commonly set to true when using with to simplify object creation, such as this example:

           def p = new Person().with(true) {
             firstName = 'John'
             lastName = 'Doe'
           }

      Alternatively, 'tap' is an alias for 'with(true)', so that method can be used instead. The other main use case for with is when returning a value calculated using self as shown here:

           def fullName = person.with(false){ "$firstName $lastName" }

      Alternatively, 'with' is an alias for 'with(false)', so the boolean parameter can be ommitted instead.
      Parameters:
        `self` - the object to have a closure act upon
        `returning` - if true, return the self object; otherwise, the result of calling the closure
        `closure` - the closure to call on the object
      Returns:
        the self object or the result of calling the closure depending on 'returning'

    - #### tap

          public static <T,U> U tap(U self,
                                    @DelegatesTo(value=DelegatesTo.Target.class,target="self",strategy=1)
                                    Closure<T> closure)

      Allows the closure to be called for the object reference self (similar to `with` and always returns self.

      Any method invoked inside the closure will first be invoked on the self reference. For instance, the following method calls to the append() method are invoked on the StringBuilder instance:

           def b = new StringBuilder().tap {
             append('foo')
             append('bar')
           }
           assert b.toString() == 'foobar'

      This is commonly used to simplify object creation, such as this example:

           def p = new Person().tap {
             firstName = 'John'
             lastName = 'Doe'
           }

      Parameters:
        `self` - the object to have a closure act upon
        `closure` - the closure to call on the object
      Returns:
        self

    - #### isCase

          public static boolean isCase(java.lang.Object caseValue,
                                       java.lang.Object switchValue)

      Method for overloading the behavior of the 'case' method in switch statements. The default implementation handles arrays types but otherwise simply delegates to Object#equals, but this may be overridden for other types. In this example:

           switch( a ) {
             case b: //some code
           }

      "some code" is called when `b.isCase( a )` returns `true`.
      Parameters:
        `caseValue` - the case value
        `switchValue` - the switch value
      Returns:
        true if the switchValue is deemed to be equal to the caseValue
      Since:
        1.0

    - #### isCase

          public static boolean isCase(java.lang.Class caseValue,
                                       java.lang.Object switchValue)

      Special 'Case' implementation for Class, which allows testing for a certain class in a switch statement. For example:

          switch( obj ) {
             case List :
               // obj is a list
               break;
             case Set :
               // etc
           }

      Parameters:
        `caseValue` - the case value
        `switchValue` - the switch value
      Returns:
        true if the switchValue is deemed to be assignable from the given class

                                       java.lang.Object switchValue)

      'Case' implementation for collections which tests if the 'switch' operand is contained in any of the 'case' values. For example:

          switch( 3 ) {
             case [1,3,5]:
               assert true
               break
             default:
               assert false
           }

      Parameters:
        `caseValue` - the case value
        `switchValue` - the switch value
      Returns:
        true if the caseValue is deemed to contain the switchValue

                                       java.lang.Object switchValue)

      'Case' implementation for maps which tests the groovy truth value obtained using the 'switch' operand as key. For example:

          switch( 'foo' ) {
             case [foo:true, bar:false]:
               assert true
               break
             default:
               assert false
           }

      Parameters:

                                       java.lang.Number switchValue)

      Special 'case' implementation for all numbers, which delegates to the `compareTo()` method for comparing numbers of different types.
      Parameters:
        `caseValue` - the case value
        `switchValue` - the switch value
      Returns:
        true if the numbers are deemed equal

      Returns an iterator equivalent to this iterator but with all duplicated items removed where duplicate (equal) items are deduced by calling the supplied Closure condition.

      If the supplied Closure takes a single parameter, the argument passed will be each element, and the closure should return a value used for comparison (either using `Comparable.compareTo(java.lang.Object)` or `Object.equals(java.lang.Object)`). If the closure takes two parameters, two items from the Iterator will be passed as arguments, and the closure should return an int value (with 0 indicating the items are not unique).

           def items = "Hello".toList() + [null, null] + "there".toList()
           def toLower = { it == null ? null : it.toLowerCase() }

           assert ![2:3, 4:5, 5:10].any { entry -> entry.key == entry.value * 2 }

      Parameters:
        `self` - the map over which we iterate
        `predicate` - the 1 or 2 arg closure predicate used for matching
      Returns:
        true if any entry in the map matches the closure predicate

               [(value*10): key.toUpperCase()] } == [10:'A', 20:'B', 30:'C']

      Note: When using the list-style of result, the behavior is '`def (key, value) = listResultFromClosure`'. While we strongly discourage using a list of size other than 2, Groovy's normal semantics apply in this case; throwing away elements after the second one and using null for the key or value for the case of a shortened list. If your collector Map doesn't support null keys or values, you might get a runtime error, e.g. NullPointerException or IllegalArgumentException.
      Parameters:
        `self` - a Map
        `collector` - the Map into which the transformed entries are put
        `transform` - the closure used for transforming, which can take one (Map.Entry) or two (key, value) parameters and should return a Map.Entry, a Map or a two-element list containing the resulting key and value

      If the `self` map is one of TreeMap, LinkedHashMap, Hashtable or Properties, the returned Map will preserve that type, otherwise a HashMap will be returned.

      Example usage:

           def result = [a:1, b:2, c:4, d:5].findAll { it.value % 2 == 0 }
           assert result.every { it instanceof Map.Entry }
           assert result*.key == ["b", "c"]
           assert result*.value == [2, 4]

      Parameters:
        `self` - a Map
        `closure` - a 1 or 2 arg Closure condition applying on the entries
      Returns:
        a new subMap

                                                 Closure<V> closure)

      Performs the same function as the version of inject that takes an initial value, but uses the head of the Collection as the initial value, and iterates over the tail.

           assert 1 * 2 * 3 * 4 == [ 1, 2, 3, 4 ].inject { acc, val -> acc * val }
           assert ['b'] == [['a','b'], ['b','c'], ['d','b']].inject { acc, val -> acc.intersect( val ) }
           LinkedHashSet set = [ 't', 'i', 'm' ]
           assert 'tim' == set.inject { a, b -> a + b }

      Parameters:
        `self` - a Collection
        `closure` - a closure
      Returns:
        the result of the last closure call
      Throws:
        `java.util.NoSuchElementException` - if the collection is empty.

      Iterates through the given Collection, passing in the initial value to the 2-arg closure along with the first item. The result is passed back (injected) into the closure along with the second item. The new result is injected back into the closure along with the third item and so on until the entire collection has been used. Also known as `foldLeft` or `reduce` in functional parlance. Examples:

           assert 1*1*2*3*4 == [1,2,3,4].inject(1) { acc, val -> acc * val }

           assert 0+1+2+3+4 == [1,2,3,4].inject(0) { acc, val -> acc + val }

           assert 'The quick brown fox' ==

      Selects the item in the iterable which when passed as a parameter to the supplied closure returns the minimum value. A null return value represents the least possible return value. If more than one item has the minimum value, an arbitrary choice is made between the items having the minimum value.

      If the closure has two parameters it is used like a traditional Comparator. I.e. it should compare its two parameters for order, returning a negative integer, zero, or a positive integer when the first parameter is less than, equal to, or greater than the second respectively. Otherwise, the Closure is assumed to take a single parameter and return a Comparable (typically an Integer) which is then used for further comparison.

           assert "hi" == ["hello","hi","hey"].min { it.length() }

           def lastDigit = { a, b -> a % 10 <=> b % 10 }

      Parameters:
        `self` - an Iterable
        `closure` - a 1 or 2 arg Closure used to determine the correct ordering
      Returns:

    - #### min

          public static <T> T min(java.util.Iterator<T> self,
                                  Closure closure)

      Selects the minimum value found from the Iterator using the closure to determine the correct ordering. The iterator will become exhausted of elements after this operation.

      If the closure has two parameters it is used like a traditional Comparator. I.e. it should compare its two parameters for order, returning a negative integer, zero, or a positive integer when the first parameter is less than, equal to, or greater than the second respectively. Otherwise, the Closure is assumed to take a single parameter and return a Comparable (typically an Integer) which is then used for further comparison.

      Parameters:
        `self` - an Iterator
        `closure` - a Closure used to determine the correct ordering
      Returns:
        the minimum value

      Selects the item in the iterable which when passed as a parameter to the supplied closure returns the maximum value. A null return value represents the least possible return value, so any item for which the supplied closure returns null, won't be selected (unless all items return null).

      If the closure has two parameters it is used like a traditional Comparator. I.e. it should compare its two parameters for order, returning a negative integer, zero, or a positive integer when the first parameter is less than, equal to, or greater than the second respectively. Otherwise, the Closure is assumed to take a single parameter and return a Comparable (typically an Integer) which is then used for further comparison.

        `self` - an Iterable
        `closure` - a 1 or 2 arg Closure used to determine the correct ordering

           iter = items.iterator()
           assert iter[1] == "a"
           // iter partially exhausted so now idx starts after "a"
           assert iter[0] == 5.3

      Parameters:
        `self` - an Iterator
        `idx` - an index value (-self.size() <= idx < self.size())

      Parameters:
        `self` - an Iterable
        `idx` - an index value (-self.size() <= idx < self.size()) but using -ve index values will be inefficient

      Returns a new `Map` containing all entries from `left` and `right`, giving precedence to `right`. Any keys appearing in both Maps will appear in the resultant map with values from the `right` operand.

      Wraps a map using the decorator pattern with a wrapper that intercepts all calls to `get(key)`. If an unknown key is found, a default value will be stored into the Map before being returned. The default value stored will be the result of calling the supplied Closure with the key as the parameter to the Closure. Example usage:

           def map = [a:1, b:2].withDefault{ k -> k.toCharacter().isLowerCase() ? 10 : -10 }
           def expected = [a:1, b:2, c:10, D:-10]
           assert expected.every{ e -> e.value == map[e.key] }

           def constMap = [:].withDefault{ 42 }
           assert constMap.foo == 42
           assert constMap.size() == 1

      Parameters:
        `self` - a Map
        `init` - a Closure which is passed the unknown key

      An alias for `withLazyDefault` which decorates a list allowing it to grow when called with index values outside the normal list bounds.
      Parameters:
        `self` - a List
        `init` - a Closure with the target index as parameter which generates the default value
      Returns:

    - #### withLazyDefault

          public static <T> ListWithDefault<T> withLazyDefault(java.util.List<T> self,
                                                               Closure<T> init)

      Decorates a list allowing it to grow when called with a non-existent index value. When called with such values, the list is grown in size and a default value is placed in the list by calling a supplied `init` Closure. Subsequent retrieval operations if finding a null value in the list assume it was set as null from an earlier growing operation and again call the `init` Closure to populate the retrieved value; consequently the list can't be used to store null values.

      How it works: The decorated list intercepts all calls to `getAt(index)` and `get(index)`. If an index greater than or equal to the current `size()` is used, the list will grow automatically up to the specified index. Gaps will be filled by `null`. If a default value should also be used to fill gaps instead of `null`, use `withEagerDefault`. If `getAt(index)` or `get(index)` are called and a null value is found, it is assumed that the null value was a consequence of an earlier grow list operation and the `init` Closure is called to populate the value.

      Example usage:

           def list = [0, 1].withLazyDefault{ 42 }
           assert list[0] == 0
           assert list[1] == 1
           assert list[3] == 42   // default value
           assert list == [0, 1, null, 42] // gap filled with null

           // illustrate using the index when generating default values
           def list2 = [5].withLazyDefault{ index -> index * index }
           assert list2[3] == 9
           assert list2 == [5, null, null, 9]
           assert list2[2] == 4
           assert list2 == [5, null, 4, 9]

           // illustrate what happens with null values
           list2[2] = null
           assert list2[2] == 4

      Parameters:
        `self` - a List

                                                           Closure closure)

      Sorts the given iterator items into a sorted iterator using the Closure to determine the correct ordering. The original iterator will be fully processed after the method call.

      If the closure has two parameters it is used like a traditional Comparator. I.e. it should compare its two parameters for order, returning a negative integer, zero, or a positive integer when the first parameter is less than, equal to, or greater than the second respectively. Otherwise, the Closure is assumed to take a single parameter and return a Comparable (typically an Integer) which is then used for further comparison.

      Parameters:
        `self` - the Iterator to be sorted
        `closure` - a Closure used to determine the correct ordering
      Returns:
        the sorted items as an Iterator

           def list = ["a", false, 2]
           assert list.pop() == 'a'
           assert list == [false, 2]

      This is similar to pop on a Stack where the first item in the list represents the top of the stack. Note: The behavior of this method changed in Groovy 2.5 to align with Java. If you need the old behavior use 'removeLast'.
      Parameters:

      Returns a new `Map` containing all entries from `self` and `entries`, giving precedence to `entries`. Any keys appearing in both Maps will appear in the resultant map with values from the `entries` operand. If `self` map is one of TreeMap, LinkedHashMap, Hashtable or Properties, the returned Map will preserve that type, otherwise a HashMap will be returned.
      Parameters:
        `self` - a Map
        `entries` - a Collection of Map.Entry items to be added to the Map.
      Returns:
        a new Map containing all key, value pairs from self and entries

           list.push("x")
           assert list == ['x', 3, 4, 2]

      This is similar to push on a Stack where the first item in the list represents the top of the stack. Note: The behavior of this method changed in Groovy 2.5 to align with Java. If you need the old behavior use 'add'.
      Parameters:
        `self` - a List
        `value` - element to be prepended to this list.
      Returns:
        `true` (for legacy compatibility reasons).

      Creates a new List by inserting all of the elements in the specified array to the elements from the original List at the specified index. Shifts the element currently at that index (if any) and any subsequent elements to the right (increasing their indices). The new elements will appear in the resulting List in the order that they occur in the original array. The behavior of this operation is undefined if the list or array operands are modified while the operation is in progress. The original list and array operands remain unchanged.

      Compare the contents of two Sets for equality using Groovy's coercion rules.

      Returns `true` if the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). If numbers exist in the sets, then they are compared as numbers, for example 2 == 2L. If both sets are `null`, the result is true; otherwise if either set is `null`, the result is `false`. Example usage:

           Set s1 = ["a", 2]
           def s2 = [2, 'a'] as Set
           Set s3 = [3, 'a']

      Overloads the left shift operator to provide an easy way to put one maps entries into another map. This allows the compact syntax `map1 << map2`; otherwise it's just a synonym for `putAll` though it returns the original map rather than being a `void` method. Example usage:

          def map = [a:1, b:2]
           map << [c:3, d:4]
           assert map == [a:1, b:2, c:3, d:4]
