Structural Pattern
Decouple instances from their classes so that those classes can be implemented as instances of a class. Type Object allows new "classes" to be created dynamically at runtime, lets a system provide its own type−checking rules, and can lead to simpler, smaller systems.
Architectural Pattern
The View Handler design pattern helps to manage all views that a software system provides. A view handler component allows clients to open, manipulate and dispose of views. It also coordinates dependencies between views and organises their update.
Behavioral Pattern
The visitor pattern is used to separate a relatively complex set of structured data classes from the functionality that may be performed upon the data that they hold.
Structural Pattern
The Whole-Part design pattern helps with the aggregation of components that together form a semantic unit. An aggregate component, the Whole, encapsulates it constituent components, the Parts, organises their collaboration, and provides a common interface to its functionality. Direct access to the Parts is not possible.
Configuration Pattern
The Wrapper Facade design pattern encapsulates low-level functions and data structures within more concise, robust, portable, and maintainable object-oriented class interfaces.
