io.realm.mongodb.functions

java.lang.Object
io.realm.mongodb.functions.Functions

A Functions manager to call remote Realm functions for the associated Realm App.Arguments and results are encoded/decoded with the Functions' codec registry either inherited from the AppConfiguration.getDefaultCodecRegistry() or set explicitly when creating the

Functions-instance through User.getFunctions(CodecRegistry) or through the individual calls to callFunction(String, List, Class, CodecRegistry) .
