Method Detail

addContextValue

<T> MethodDescriptor.Rules<ReqT,ResT> addContextValue(io.grpc.Context.Key<T> key,
                                                            T value)

Add a Context.Key and value to be added to the call Context when this method is invoked.

Type Parameters:

T - the type of the Context.Key and value

Parameters:

key - the Context.Key to add

value - the value to map to the Context.Key

Returns:

this MethodDescriptor.Rules instance for fluent call chaining

Throws:

NullPointerException - if the key parameter is null

intercept

MethodDescriptor.Rules<ReqT,ResT> intercept(io.grpc.ServerInterceptor... interceptors)

Register one or more interceptors for the method.

Parameters:

interceptors - one or more ServerInterceptors to register

Returns:

this builder to allow fluent method chaining

intercept

MethodDescriptor.Rules<ReqT,ResT> intercept(int priority,
                                                  io.grpc.ServerInterceptor... interceptors)

Register one or more interceptors for the method.

The added interceptors will be applied using the specified priority.

Parameters:

priority - the priority to assign to the interceptors

interceptors - one or more ServerInterceptors to register

Returns:

this builder to allow fluent method chaining

marshallerSupplier

MethodDescriptor.Rules<ReqT,ResT> marshallerSupplier(MarshallerSupplier marshallerSupplier)

Register the MarshallerSupplier for the method.

If not set the default MarshallerSupplier from the service will be used.

Parameters:

marshallerSupplier - the MarshallerSupplier for the service

Returns:

this ServiceDescriptor.Rules instance for fluent call chaining

requestType

<Rnew> MethodDescriptor.Rules<Rnew,ResT> requestType(Class<Rnew> requestType)

Set the request type.

Setting the request type is optional as it is used to obtain the correct marshaller so if the marshaller supplier being used is type agnostic, such as Java serialization then whereas some marshallers such as Protocol Buffers require a type.

Type Parameters:

Rnew - the type of the request message

Parameters:

requestType - the type of the request message

Returns:

this ServiceDescriptor.Rules instance for fluent call chaining

responseType

<Rnew> MethodDescriptor.Rules<ReqT,Rnew> responseType(Class<Rnew> responseType)

Set the response type.

Setting the response type is optional as it is used to obtain the correct marshaller so if the marshaller supplier being used is type agnostic, such as Java serialization then whereas some marshallers such as Protocol Buffers require a type.

Type Parameters:

Rnew - the type of the request message

Parameters:

responseType - the type of the request message

Returns:

this ServiceDescriptor.Rules instance for fluent call chaining
