限定符和类型	方法和说明
boolean	AbstractKeyedStateBackend.deregisterKeySelectionListener(KeyedStateBackend.KeySelectionListener<K> listener)
boolean	KeyedStateBackend.deregisterKeySelectionListener(KeyedStateBackend.KeySelectionListener<K> listener) Stop calling listener registered in KeyedStateBackend.registerKeySelectionListener(org.apache.flink.runtime.state.KeyedStateBackend.KeySelectionListener<K>).
void	AbstractKeyedStateBackend.registerKeySelectionListener(KeyedStateBackend.KeySelectionListener<K> listener)
void	KeyedStateBackend.registerKeySelectionListener(KeyedStateBackend.KeySelectionListener<K> listener) State backend will call keySelected(K) when key context is switched if supported.
