类概要

类	说明
BootstrapTransformation<T>	A BootstrapTransformation represents a procedure of writing new operator state into a Savepoint.
EvictingWindowReader<W extends org.apache.flink.streaming.api.windowing.windows.Window>	This class provides entry points for reading keyed state written out using the WindowOperator.
ExistingSavepoint	An existing savepoint.
KeyedOperatorTransformation<K,T>	A KeyedOperatorTransformation represents a OneInputOperatorTransformation on which operator state is partitioned by key using a provided KeySelector.
NewSavepoint	A new savepoint.
OneInputOperatorTransformation<T>	OneInputOperatorTransformation represents a user defined transformation applied on an OperatorTransformation with one input.
OperatorTransformation	This class provides the entry point for building BootstrapTransformations, which represents procedures to bootstrap new operator states with a given DataSet.
Savepoint	This class provides entry points for loading an existing savepoint, or a new empty savepoint.
WindowedOperatorTransformation<T,K,W extends org.apache.flink.streaming.api.windowing.windows.Window>	A WindowedOperatorTransformation represents a OneInputOperatorTransformation for bootstrapping window state.
WindowReader<W extends org.apache.flink.streaming.api.windowing.windows.Window>	This class provides entry points for reading keyed state written out using the WindowOperator.
WritableSavepoint<F extends WritableSavepoint>	A WritableSavepoint is any savepoint that can be written to from a batch context.
