- - io.helidon.microprofile.grpc.core.UnaryMethodHandlerSupplier.AbstractUnaryHandler<ReqT,RespT>
  - - io.helidon.microprofile.grpc.core.UnaryMethodHandlerSupplier.RequestResponse<ReqT,RespT>

Type Parameters:

ReqT - the request type

RespT - the response type

All Implemented Interfaces:

io.grpc.stub.ServerCalls.BidiStreamingMethod<ReqT,RespT>, io.grpc.stub.ServerCalls.ClientStreamingMethod<ReqT,RespT>, io.grpc.stub.ServerCalls.ServerStreamingMethod<ReqT,RespT>, io.grpc.stub.ServerCalls.UnaryMethod<ReqT,RespT>, MethodHandler<ReqT,RespT>

Enclosing class:

UnaryMethodHandlerSupplier
```
public static class UnaryMethodHandlerSupplier.RequestResponse<ReqT,RespT>
extends UnaryMethodHandlerSupplier.AbstractUnaryHandler<ReqT,RespT>
```
A unary MethodHandler that calls a handler method of the form.
```
     RestT invoke(ReqT request)
 
```

    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
