RegisterParser()

size_t grpc_core::ServiceConfigParser::RegisterParser ( std::unique_ptr< Parser >  parser )

static

Globally register a service config parser.

On successful registration, it returns the index at which the parser was registered. On failure, -1 is returned. Each new service config update will go through all the registered parser. Each parser is responsible for reading the service config json and returning a parsed config. This parsed config can later be retrieved using the same index that was returned at registration time.

Shutdown()

void grpc_core::ServiceConfigParser::Shutdown ( )
