SYNOPSIS

13           use DateTime::Format::Builder
14           (
15               parsers => {
16                   parse_datetime => [
17                       {
18                           Dispatch => sub {
19                               return 'fnerk';
20                           }
21                       }
22                   ]
23               },
24               groups => {
25                   fnerk => [
26                       {
27                           regex => qr/^(\d{4})(\d\d)(\d\d)$/,
28                           params => [qw( year month day )],
29                       },
30                   ]
31               }
32           );

DESCRIPTION

35       "Dispatch" adds another parser type to "Builder" permitting dispatch of
36       parsing according to group names.
37

SPECIFICATION

39       "Dispatch" has just one key: "Dispatch". The value should be a
40       reference to a subroutine that returns one of:
41
42       ·   "undef", meaning no groups could be found.
43
44       ·   An empty list, meaning no groups could be found.
45
46       ·   A single string, meaning: use this group
47
48       ·   A list of strings, meaning: use these groups in this order.
49
50       Groups are specified much like the example in the SYNOPSIS.  They
51       follow the same format as when you specify them for methods.
52

SIDEEFFECTS

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