Class GenericFieldBroadcaster

org.web3d.vrml.scripting.external.neteai.GenericFieldBroadcaster

All Implemented Interfaces:

FieldBroadcaster

public class GenericFieldBroadcaster
extends Object
implements FieldBroadcaster

Simple implementation of the FieldBroadcaster interface. This broadcaster must use a separate broadcasting thread because ClientProcessingTask's thread can't be used for processing user requests (it ends up blocking and waiting for itself).
