Constructor Details

This class inherits a constructor from PSD::Node::Base

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

If the method is missing, we blindly send it to the layer. The layer handles the case in which the method doesn’t exist.
