SYNOPSIS

12           package SampleDispatch;
13           use DateTime::Format::Builder (
14               parsers => {
15                   parse_datetime => [
16                       {
17                           Dispatch => sub {
18                               return 'fnerk';
19                           }
20                       }
21                   ]
22               },
23               groups => {
24                   fnerk => [
25                       {
26                           regex  => qr/^(\d{4})(\d\d)(\d\d)$/,
27                           params => [qw( year month day )],
28                       },
29                   ]
30               }
31           );

DESCRIPTION

34       "Dispatch" adds another parser type to "Builder" permitting dispatch of
35       parsing according to group names.
36

SPECIFICATION

38       "Dispatch" has just one key: "Dispatch". The value should be a
39       reference to a subroutine that returns one of:
40
41       •   "undef", meaning no groups could be found.
42
43       •   An empty list, meaning no groups could be found.
44
45       •   A single string, meaning: use this group
46
47       •   A list of strings, meaning: use these groups in this order.
48
49       Groups are specified much like the example in the SYNOPSIS. They follow
50       the same format as when you specify them for methods.
51

SIDE EFFECTS

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