Uses of StateObject in org.apache.flink.runtime.state

Subinterfaces of StateObject in org.apache.flink.runtime.state

Modifier and Type	Interface and Description
interface	KvStateSnapshot<K,N,S extends org.apache.flink.api.common.state.State,SD extends org.apache.flink.api.common.state.StateDescriptor<S,?>,Backend extends AbstractStateBackend> This class represents a snapshot of the KvState, taken for a checkpoint.
interface	StateHandle<T> StateHandle is a general handle interface meant to abstract operator state fetching.
interface	StreamStateHandle A state handle that produces an input stream when resolved.

Classes in org.apache.flink.runtime.state that implement StateObject

Modifier and Type	Class and Description
class	AsynchronousKvStateSnapshot<K,N,S extends org.apache.flink.api.common.state.State,SD extends org.apache.flink.api.common.state.StateDescriptor<S,?>,Backend extends AbstractStateBackend> KvStateSnapshot that asynchronously materializes the state that it represents.
class	AsynchronousStateHandle<T> StateHandle that can asynchronously materialize the state that it represents.
class	LocalStateHandle<T extends Serializable> A StateHandle that includes the operator states directly.
