Method Details

invoke

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

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

Invoke the actual unary or server streaming 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

request - the method request

observer - the method response observer

Throws:

InvocationTargetException - if an error occurs invoking the method

IllegalAccessException - if the method cannot be accessed

unary

public Object unary(Object[] args,
 MethodHandler.UnaryClient client)

Invoke the client call.

The call is from a method signature:

     RestT invoke(ReqT request);
 

so the request is in args[0].

Parameters:

args - the call arguments.

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

Returns:

the request response
