NAME

Devel::Events::Filter::Drop - Remove events that match or don’t match a condition.

CONTENTS

SYNOPSIS



        use Devel::Events::Filter::Drop;

        my $f = Devel::Events::Filter::Drop->new(
                match        => $cond, # see Devel::Events::Match
                non_matching => 1,     # invert so that nonmatching events get dropped
                handler      => $h,
        );



DESCRIPTION

This filter allows dropping of events that match (or that don’t match) a condition. The actual matching is done by Devel::Events::Match.

ATTRIBUTES

match The condition to be passed to compile_cond in Devel::Events::Match.
matcher An instance of Devel::Events::Match used to compile match.
non_matching Drop events that don’t match the condition, instead of ones that do.

METHODS

filter_event @event Delegates to the compiled condition and then returns the event unaltered or returns nothing based on the values of non_matching and the result of the match.
