Class StateHandleID

java.lang.Object

org.apache.flink.util.StringBasedID

org.apache.flink.runtime.state.StateHandleID

All Implemented Interfaces:

Serializable

public class StateHandleID
extends org.apache.flink.util.StringBasedID

Unique ID that allows for logical comparison between state handles.

Two state handles that are considered as logically equal should always return the same ID (whatever logically equal means is up to the implementation). For example, this could be based on the string representation of the full filepath for a state that is based on a file.
