Editing Decorator pattern (section)

=== Obstacles of interfacing with decorators === 
Applying combinations of decorators in diverse ways to a collection of objects introduces some problems interfacing with the collection in a way that takes full advantage of the functionality added by the decorators. The use of an [[Adapter Pattern|Adapter]] or [[Visitor Pattern|Visitor]] patterns can be useful in such cases. Interfacing with multiple layers of decorators poses additional challenges and logic of Adapters and Visitors must be designed to account for that.
