DateTime::Format::BuilUser:ContriDateTime::Format::Builder::Parser::generic(3)

NAME
       DateTime::Format::Builder::Parser::generic - Useful routines

METHODS
   Useful
       new

       Standard constructor. Returns a blessed hash; any arguments are placed
       in the hash. This is useful for storing information between methods.

       generic_parser

       This is a method provided solely for the benefit of "Parser"
       implementations. It semi-neatly abstracts a lot of the work involved.

       Basically, it takes parameters matching the assorted callbacks from the
       parser declarations and makes a coderef out of it all.

       Currently recognized callbacks are:

       ·   on_match

       ·   on_fail

       ·   preprocess

       ·   postprocess

   Methods for subclassing
       These are methods you should define when writing your own subclass.

       Note: these methods do not exist in this class. There is no point
       trying to call "$self->SUPER::do_match( ... )".

       do_match

       "do_match" is the first phase. Arguments are the date and @args.
       "self", "label", "args". Return value must be defined if you match
       successfully.

       post_match

       "post_match" is called after the appropriate callback out of
       "on_match"/"on_fail" is done. It's passed the date, the return value
       from "do_match" and the parsing hash.

       Its return value is used as the "post" argument to the "postprocess"
       callback, and as the second argument to "make".

       make

       "make" takes the original input, the return value from "post_match" and
       the parsing hash and should return a "DateTime" object or undefined.

   Delegations
       For use of "Parser", this module also delegates "valid_params" and
       "params". This is just convenience to save typing the following:

	   DateTime::Format::Builder::Parser->valid_params( blah )

       Instead we get to type:

	   $self->valid_params( blah );
	   __PACKAGE__->valid_params( blah );

WRITING A SUBCLASS
       Rather than attempt to explain how it all works, I think it's best if
       you take a look at Regex.pm and Strptime.pm as examples and work from
       there.

SUPPORT
       Support for this module is provided via the datetime@perl.org email
       list. See http://lists.perl.org/ for more details.

       Alternatively, log them via the CPAN RT system via the web or email:

	   http://perl.dellah.org/rt/dtbuilder
	   bug-datetime-format-builder@rt.cpan.org

       This makes it much easier for me to track things and thus means your
       problem is less likely to be neglected.
