type MapperType 

type MapperType int

MapperType is the mapper type

	// You can register any number of hookhandler to handle the rest process.
	// When each conncection is intantiated, the hookhandler remain in memory until the REST op is returned
	// If there are two hookhandler which handles the same method and the same hook, they will both be called.
