Interface Receivers

All Known Implementing Classes:

ReceiversImpl, ReceiversImplArrayList, ReceiversImplLinkedList

public interface Receivers

Interface to be implemented by a receivers implementation. The implementation should also have a default constructor.

NOTE: There is no need to internally synchronize the caller handles that.

NOTE: This datastructure should have Set semantics. i.e. attempts to add a subscriber that is already present should be ignored. Or more explicitly a subscriber should present zero or once.
