Examples of com.google.protobuf.Service.callMethod()

com.google.protobuf.Service.callMethod()
Call a method of the service specified by MethodDescriptor. This is normally implemented as a simple {@code switch()} that calls the standarddefinitions of the service's methods.
Preconditions:
- {@code method.getService() == getDescriptorForType()}
- {@code request} is of the exact same class as the object returned by{@code getRequestPrototype(method)}.
- {@code controller} is of the correct type for the RPC implementationbeing used by this Service. For stubs, the "correct type" depends on the RpcChannel which the stub is using. Server-side Service implementations are expected to accept whatever type of {@code RpcController} the server-side RPC implementation uses.
Postconditions:
- {@code done} will be called when the method is complete. This may bebefore {@code callMethod()} returns or it may be at some point inthe future.
- The parameter to {@code done} is the response. It must be of theexact same type as would be returned by {@code getResponsePrototype(method)}.
- If the RPC failed, the parameter to {@code done} will be{@code null}. Further details about the failure can be found by querying {@code controller}.
