=head2 class
-Returns the class name where this action is defined.
+Returns the name of the component where this action is defined.
+Derived by calling the L<catalyst_component_name|Catalyst::Component/catalyst_component_name>
+method on each component.
=head2 code
=head2 dispatch( $c )
-Dispatch this action against a context
+Dispatch this action against a context.
=head2 execute( $controller, $c, @args )
Check Args attribute, and makes sure number of args matches the setting.
Always returns true if Args is omitted.
+=head2 match_captures ($c, $captures)
+
+Can be implemented by action class and action role authors. If the method
+exists, then it will be called with the request context and an array reference
+of the captures for this action.
+
+Returning true from this method causes the chain match to continue, returning
+makes the chain not match (and alternate, less preferred chains will be attempted).
+
+
=head2 compare
Compares 2 actions based on the value of the C<Args> attribute, with no C<Args>
having the highest precedence.
-C<< <=> >> is overloaded to use this method.
-
=head2 namespace
Returns the private namespace this action lives in.
Returns the private path for this action.
+=head2 private_path
+
+Returns absolute private path for this action. Unlike C<reverse>, the
+C<private_path> of an action is always suitable for passing to C<forward>.
+
=head2 name
-returns the sub name of this action.
+Returns the sub name of this action.
+
+=head2 number_of_args
+
+Returns the number of args this action expects. This is 0 if the action doesn't take any arguments and undef if it will take any number of arguments.
+
+=head2 number_of_captures
+
+Returns the number of captures this action expects for L<Chained|Catalyst::DispatchType::Chained> actions.
+
+=head2 list_extra_info
+
+A HashRef of key-values that an action can provide to a debugging screen
+
+=head2 scheme
+
+Any defined scheme for the action
