Interface ServiceLocationEnumeration

All Superinterfaces:
Enumeration
Known Implementing Classes:
SLEnumerationImpl

public interface ServiceLocationEnumeration
extends Enumeration

The ServiceLocationEnumeration class is the return type for all Locator SLP operations. The Java API library may implement this class to block until results are available from the SLP operation, so that the client can achieve asynchronous operation by retrieving results from the enumeration in a separate thread. Clients use the superclass nextElement() method if they are unconcerned with SLP exceptions (this method will never ever throw one).
