Uses of CompositeStateHandle in org.apache.flink.runtime.checkpoint

Classes in org.apache.flink.runtime.checkpoint that implement CompositeStateHandle

Modifier and Type	Class	Description
class	FinishedOperatorSubtaskState	A specialized OperatorSubtaskState representing the subtask is finished.
class	FullyFinishedOperatorState	A special operator state implementation representing the operators whose instances are all finished.
class	OperatorState	Simple container class which contains the raw/managed operator state and key-group state handles from all subtasks of an operator and therefore represents the complete state of a logical operator.
class	OperatorSubtaskState	This class encapsulates the state for one parallel instance of an operator.
class	SubtaskState	Deprecated. Internal class for savepoint backwards compatibility.
class	TaskState	Deprecated. Internal class for savepoint backwards compatibility.
class	TaskStateSnapshot	This class encapsulates state handles to the snapshots of all operator instances executed within one task.
