The type of the expected source request. Specifying this explicitly
is usually sufficient to allow type inference to work for generic methods within this class.
public static CallInvoker Create<TSourceResponse, TTargetRequest, TTargetResponse>(CallInvoker originalInvoker, string sourceMethodFullName, Method<TTargetRequest, TTargetResponse> targetMethod, Func<TSourceRequest, TTargetRequest> requestConverter, Func<TSourceRequest, TTargetResponse, TSourceResponse> responseConverter) where TSourceResponse : class where TTargetRequest : class where TTargetResponse : class
Creates a Google.Api.Gax.Grpc.ForwardingCallInvoker`4
to forward a single unary call to a method in an existing .
Parameters
