Method Detail

clientOnly

public boolean clientOnly()

Description copied from interface: MethodHandler

Determine whether this is a client side only handler.

Returns:

true if this handler can only be used on the client

invoke

protected io.grpc.stub.StreamObserver<ReqT> invoke(Method method,
                                                   Object instance,
                                                   io.grpc.stub.StreamObserver<RespT> observer)
                                            throws InvocationTargetException,
                                                   IllegalAccessException

Description copied from class: io.helidon.microprofile.grpc.core.AbstractMethodHandlerSupplier.AbstractHandler

Invoke the actual client streaming or bi-directional gRPC method handler.

Specified by:

invoke in class io.helidon.microprofile.grpc.core.AbstractMethodHandlerSupplier.AbstractHandler<ReqT,RespT>

Parameters:

method - the Method to invoke

instance - the service instance to invoke the method on

observer - the method response observer

Returns:

the StreamObserver to receive requests from the client

Throws:

InvocationTargetException - if an error occurs invoking the method

IllegalAccessException - if the method cannot be accessed

clientStreaming

public Object clientStreaming(Object[] args,
                              MethodHandler.ClientStreaming client)

Description copied from interface: MethodHandler

Handle a bi-directional client call.

Parameters:

args - the call arguments.

client - the MethodHandler.ClientStreaming instance to forward the call to.

Returns:

the call result
