 Class/object composition
+  * Adapter/Wrapper: Adapter realizes interfaces, uses method of external class
+  * Bridge: Hierarchy of abstractions and implementations
+  * Facade: Unified, simplified interface to complex operations involving multiple classes
+  * Decorator: Dynamically add/remove methods to an object
+  * Flyweight: Large number of object required, where information is shared
+  * Composite: Tree-structure to represent part-whole hierarchies (treat part and whole uniformly)
+  * Proxy: Class acting as interface to something else.
 ===== Verhaltensmuster (behavioral patterns) =====
+  * Template method: Abstract class which implements invariant code and helper method, while specific implementations are in derived classes
+  * Strategy: Defines interface for a method and concrete implementations. Strategies could be choosen on runtime.
+  * Iterator: Access of elements in container without exposing underlying representation
+  * Interpreter: Using Composite e.g. with Terminal/NonTerminal class representations e.g. to implement an abstract syntax tree
