SYNOPSIS

12          my $parser = DateTime::Format::Builder->create_parser(
13               regex  => qr/^(\d\d\d\d)(\d\d)(\d\d)T(\d\d)(\d\d)(\d\d)$/,
14               params => [ qw( year month day hour minute second ) ],
15          );

SPECIFICATION

18       In addition to the common keys, "Regex" supports:
19
20       ·   regex is a regular expression that should capture elements of the
21           datetime string.  This is a required element. This is the key whose
22           presence indicates it's a specification that belongs to this class.
23
24       ·   params is an arrayref of key names. The captures from the regex are
25           mapped to these ($1 to the first element, $2 to the second, and so
26           on) and handed to "DateTime->new()".  This is a required element.
27
28       ·   extra is a hashref of extra arguments you wish to give to
29           "DateTime->new()". For example, you could set the "year" or
30           "time_zone" to defaults:
31
32               extra => { year => 2004, time_zone => "Australia/Sydney" },
33
34       ·   constructor is either an arrayref or a coderef. If an arrayref then
35           the first element is a class name or object, and the second element
36           is a method name (or coderef since Perl allows that sort of thing).
37           The arguments to the call are anything in $p and anything given in
38           the "extra" option above.
39
40           If only a coderef is supplied, then it is called with arguments of
41           $self, $p and "extra".
42
43           In short:
44
45                       $self->$coderef( %$p, %{ $self->{extra} } );
46
47           The method is expected to return a valid DateTime object, or undef
48           in event of failure, but can conceivably return anything it likes.
49           So long as it's 'true'.
