void DataStorm::Writer< Key, Value, UpdateTag >::onConnectedKeys ( std::function< void(std::vector< Key >)> init, std::function< void(CallbackReason, Key)> update )

noexcept

Calls the given functions to provide the initial set of connected keys and when a key is added or removed from the set of connected keys.

If callback functions are already set, they will be replaced. The connected keys represent the set of keys for which writers are connected to this reader. The init callback is always called after this method returns to provide the initial set of connected keys. The update callback is called when new keys are added or removed from the set of connected keys.

Parameters

init	The function to call with the initial set of connected keys.
update	The function to call when a key is added or removed from the set.
