public class ChoosableComputeApplicationPattern
extends AbstractPattern

ChoosableComputeApplicationPattern The term compositor contains a set of compute applications, where the client must choose on application out of the set.

The protocol of this pattern is as follows. First one must select an application using selectApplication(ApplicationType) or selectApplication(String, String). This service selection is instantly registered in the underlying term compositor.

Subsequent modifications to the selected applications are possible by using functions such as getSelectedApplication() or getSelectedJobDefinition(). These modifications are not registered in the term compositor until updateSelectedApplication() is executed.
