VERSION

22       Workflow::Validator::MatchesDateFormat
23

DESCRIPTION

25       This validator ensures that a given date string matches a "strptime"
26       pattern. The parameter 'date_format' is used to declare the pattern
27       against which the date string must be matched, and the single argument
28       is the date to match.
29
30       The 'date_format' pattern is a typical "strptime" pattern. See
31       DateTime::Format::Strptime for details.
32
33       NOTE: If you pass an empty string (or no string) to this validator it
34       will not throw an error. Why? If you want a value to be defined it is
35       more appropriate to use the 'is_required' attribute of the input field
36       to ensure it has a value.
37
38       Also, if you pass a DateTime object to the validator it will not
39       determine whether the date is correct or within a range. As far as it
40       is concerned its job is done.
41
42   METHODS
43       _init
44
45       This method initializes the class and the enumerated class.
46
47       It uses "add_enumerated_values" to add the set of values for
48       enumeration.
49
50       The primary parameter is value, which should be used to specify the
51       either a single value or a reference to array of values to be added.
52
53       validate
54
55       The validator method is the public API. It works with Workflow.
56
57       Based on the initialized Workflow::Validator it validates a provided
58       parameter, which should adhere to a predefined date format.
