Devel::Events::Filter(User Contributed Perl DocumentatDevel::Events::Filter(3)

NAME
       Devel::Events::Filter - A handler role that filters events and
       delegates to another.

SYNOPSIS
	       package MyFilter;
	       use Moose;

	       with qw/Devel::Events::Filter/;

	       sub filter_event	{
		       my ( $self, @event ) = @_;

		       return (map { ... } @event);
	       }

DESCRIPTION
       This role allows	you to build event filters easily:

USAGE
       To use this role	you must provide the "filter_event" method.

       This role provides an optional "handler"	attribute and a	"new_event"
       method, and does	the Devel::Events::Handler role	implicitly.

       If a sub	handler	was provided then the filtered event will be delegated
       to it, but due to the usefulness	of filters as debugging	aids this is
       currently optional.

       In the future this design choice	might change.

ATTRIBUTES
       handler
	   A Devel::Events::Handler to delegate	to.

METHODS
       new_event @event
	   Filters the event through "filter_event".

	   If "handler"	is set,	delegates the filtered event to	the handler.
	   If not "no_handler_error" is	called instead.

       no_handler_error	@filtered_event
	   This	method is called if no handler is present. It is a stub, but
	   in the future it may	raise an error.
