NAME
Devel::Events::Filter - A handler role that filters events and delegates to another
VERSION
version 0.09
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 anew_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 notno_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.
