Interface ADEPT2StubFactory<S>

Type Parameters:
S - The (super) type of services this factory creates stubs for (e. g. set S to ADEPT2Service to limit stub creation to remote ADEPT2 services).
public interface ADEPT2StubFactory<S>
Submodules of the CommunicationService defined by this interface are responsible for creating stubs which represent the corresponding remote services/callback objects on remote side.

    • getServiceStub

      <T extends S> T getServiceStub(URI remoteObjectIdentifier, Class<T> remoteInterface)
      Returns the stub ready to invoke operations remotely on the service or callback object described by the given URI.
      Type Parameters:
      T - The type (interface) of the service/callback object that must be a sub type of that type this factory .
      Parameters:
      remoteObjectIdentifier - The Identifier of the service/callback object instance to create a stub for.
      remoteInterface - The interface used to access the remote service/the callback object.
      Returns:
      The stub representing the specified service/callback object on the remote host.
      Throws:
      IllegalArgumentException - If the stub can not handle the communication required by the URI.

    • getInvocationHandler

      <T extends S> InvocationHandler getInvocationHandler(URI remoteObjectIdentifier, Class<T> remoteIface, boolean create)
      Returns the InvocationHandler for the remote service/callback object that is associated with the designated remote object identifier and the designated remote interface. If the invocation handler does not exist, it will be created if appropriate.
      Parameters:
      remoteObjectIdentifier - The identifier of the requested remote service/callback object.
      remoteIface - The interface of the requested remote service/callback object.
      create - Whether the invocation handler should be created. Only let it create if you remove it later.
      Returns:
      The InvocationHandler associated with the given remoteObjectIdentifier or null if no InvocationHandler exists for the given remoteObjectIdentifier.

    • removeStub

      void removeStub(URI remoteObjectIdentifier)
      Removes the stub with the designated identifier if it is cached. This is usually used for callbacks but not for (sub-)services since services are singleton.
      Parameters:
      remoteObjectIdentifier - The identifier of the service or callback object to remove the stub from.
