Class ThreadedServiceModel

java.lang.Object
  org.apache.hivemind.impl.servicemodel.AbstractServiceModelImpl
      org.apache.hivemind.impl.servicemodel.ThreadedServiceModel

All Implemented Interfaces:: org.apache.hivemind.internal.ServiceModel

public final class ThreadedServiceModel
extends AbstractServiceModelImpl

Like SingletonServiceModel, this method returns a proxy (implementing the service interface); unlike SingletonServiceModel, it always returns the proxy. Invoking a service method on the proxy constructs a service implementation and binds it to the current thread.
