Method Detail

getServices

public final Services getServices(ServiceTemplate serviceTemplate,
                                  int maxNumMatches,
                                  Services services,
                                  boolean isLocal)

Parameters:

serviceTemplate - Desired service capabilities.

maxNumMatches - Maximum number of services to find.

services - Collection of discovered services.

isLocal - Whether local true or remote false services are desired.

Returns:

Services satisfying the requested service template.

Parameters:

service - The service to remove.

getLocalServices

public final java.util.Iterator getLocalServices()

Gets an iterator of services that are available within the local JVM process.

Returns:

Iterator for collection copy of locally available services implementing RemoteServiceInterface.
