NAME

App::Ack::Filter::IsGroup

DESCRIPTION

The App::Ack::Filter::IsGroup class optimizes multiple App::Ack::Filter::Is calls into one container.

Let's say you have 100 --type-add=is:... filters.

You could have

            

              
              
my @filters = map { make_is_filter($_) } 1..100;
            
          

and then do

            

              
              
if ( any { $_->filter($rsrc) } @filters ) { ... }
            
          

but that's slow, because of of method lookup overhead, function call overhead, etc. So ::Is filters know how to organize themselves into an ::IsGroup filter.
