NAME

6       DateTime::Format::Builder::Parser::Dispatch - Dispatch parsers by group
7

SYNOPSIS

9           package SampleDispatch;
10           use DateTime::Format::Builder
11           (
12               parsers => {
13                   parse_datetime => [
14                       {
15                           Dispatch => sub {
16                               return 'fnerk';
17                           }
18                       }
19                   ]
20               },
21               groups => {
22                   fnerk => [
23                       {
24                           regex => qr/^(\d{4})(\d\d)(\d\d)$/,
25                           params => [qw( year month day )],
26                       },
27                   ]
28               }
29           );

DESCRIPTION

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

SPECIFICATION

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

SIDEEFFECTS

51       Your group parser can also be a Dispatch parser. Thus you could poten‐
52       tially end up with an infinitely recursive parser.
