Class ICasaServiceCollection

java.lang.Object

fr.liglab.adele.icasa.dependency.manager.ICasaServiceCollection

All Implemented Interfaces:

Iterable, Collection, List, Set

public class ICasaServiceCollection
extends Object
implements Collection, List, Set

Maintains a service object collection. This collection wrap the temporal dependency to be accessible from a Collection, that can be passed to helper objects (Collaborators). The Collection.iterator() method returns an Iterator iterating on a cached copy of available service objects. In the case that there are no available services, the policies act as follows:

• 'null' returns a null iterator
• 'nullable' and default-implementation returns an iterator iterating on one object (the nullable or default-implementation object
• 'empty' returns an empty iterator.
