NAME
DateTime::Format::Builder::Parser::Dispatch - Dispatch parsers by group

SYNOPSIS
    package SampleDispatch;
    use DateTime::Format::Builder
    (
        parsers => {
            parse_datetime => [
                {
                    Dispatch => sub {
                        return 'fnerk';
                    }
                }
            ]
        },
        groups => {
            fnerk => [
                {
                    regex => qr/^(\d{4})(\d\d)(\d\d)$/,
                    params => [qw( year month day )],
                },
            ]
        }
    );

DESCRIPTION
"Dispatch" adds another parser type to "Builder" permitting dispatch of parsing according to group names.

SPECIFICATION
"Dispatch" has just one key: "Dispatch". The value should be a reference to a subroutine that returns one of:

•   "undef", meaning no groups could be found.

•   An empty list, meaning no groups could be found.

•   A single string, meaning: use this group

•   A list of strings, meaning: use these groups in this order.

Groups are specified much like the example in the SYNOPSIS. They follow the same format as when you specify them for methods.

SIDEEFFECTS
Your group parser can also be a Dispatch parser. Thus you could potentially end up with an infinitely recursive parser.

THANKS
See the main module's section.

SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details.

Alternatively, log them via the CPAN RT system via the web or email:

    http://perl.dellah.org/rt/dtbuilder
    bug-datetime-format-builder@rt.cpan.org

This makes it much easier for me to track things and thus means your problem is less likely to be neglected.
