All Implemented Interfaces:

FieldInterceptor, MethodInterceptor, DependencyStateListener

public class TemporalHandler
extends PrimitiveHandler
implements DependencyStateListener

Temporal dependency handler. A temporal dependency waits (block) for the availability of the service. If no provider arrives in the specified among of time, a runtime exception is thrown.
