NAME ^

Attribute::Method::Tags::Registry - Global registry of tags by class and method.

SYNOPSIS ^

 # tags previously created via Attribute::Method::Tags

 use Attribute::Method::Tags::Registry;

 my @tags = Attribute::Method::Tags::Registry->tags;
 foreach my $tag ( @tags ) {
     my @classes = Attribute::Method::Tags::Registry->classes_with_tag( $tag );

     foreach my $class ( @classes ) {
         my @methods = Attributes::Method::Tags::Registry->methods_with_tag( $class, $tag );

         foreach my $method ( @methods ) {
             print Attribute::Method::Tags::Registry->method_has_tag( $class, $method, $tag );
         }
     }
 }

DESCRIPTION ^

This class permits addition and querying of the tags defined on methods. It's normally meant to be used in conjunction with Attribute::Method::Tags.

classes_with_tag( $tag )

Find all classes that have the specified tag. Returns a sorted list of classes.
