   * Class pattern
-    * [[design_patterns:factorymethod|Factory Method / Virtual Constructor]]
+    * [[design_patterns:factorymethod|Factory Method / Virtual Constructor]]: Object creation via method instead of constructor
   * Object pattern
     * [[design_patterns:builder|Builder pattern]]
+  * Abstract factory pattern: Group of factories
-  * Singleton
+  * Prototype pattern: Clone method/interface
+  * Singleton pattern
+  * Multiton pattern (flyweight): Multiple objects based on key (getInstance(key), using a hashmap)
 ===== Strukturmuster (structural patterns) =====
 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
