GoF Command Pattern
Encapsulate a request as an object, thereby letting you parameterize clients with different requests,
queue or log requests, and support undoable operations.
Componentized Command Pattern
PerfectJPattern's componentized version of the Command Pattern provides the following advantages:
- Parameterizes the Invoker, Command and Receiver with generic parameter and return
types. This parameterization allow passing user-defined arguments to the Invoker and therefore
to the Command and Receiver; it also support optionally associating a possible Result value
out of the execution of the Receiver.
