Method Detail

deepCopy

@Nonnull
public RegisteredBroadcastStateBackendMetaInfo<K,V> deepCopy()

Creates a deep copy of the itself.

snapshot

@Nonnull
public StateMetaInfoSnapshot snapshot()

Specified by:

snapshot in class RegisteredStateMetaInfoBase

withSerializerUpgradesAllowed

@Nonnull
public RegisteredBroadcastStateBackendMetaInfo<K,V> withSerializerUpgradesAllowed()

Description copied from class: RegisteredStateMetaInfoBase

create a new metadata object with Lazy serializer provider using existing one as a snapshot. Sometimes metadata was just created or updated, but its StateSerializerProvider will not allow further updates. So this method could replace it with a new one that contains a fresh LazilyRegisteredStateSerializerProvider.
