Method Detail

getVersion

public int getVersion()

Deprecated.

Description copied from interface: Versioned

Returns the version number of the object. Versions numbers can be used to differentiate evolving classes.

resolveSchemaCompatibility

public TypeSerializerSchemaCompatibility<SharedBuffer<V>> resolveSchemaCompatibility(TypeSerializer<SharedBuffer<V>> newSerializer)

Deprecated.

Description copied from interface: TypeSerializerSnapshot

Checks a new serializer's compatibility to read data written by the prior serializer.

When a checkpoint/savepoint is restored, this method checks whether the serialization format of the data in the checkpoint/savepoint is compatible for the format of the serializer used by the program that restores the checkpoint/savepoint. The outcome can be that the serialization format is compatible, that the program's serializer needs to reconfigure itself (meaning to incorporate some information from the TypeSerializerSnapshot to be compatible), that the format is outright incompatible, or that a migration needed. In the latter case, the TypeSerializerSnapshot produces a serializer to deserialize the data, and the restoring program's serializer re-serializes the data, thus converting the format during the restore operation.

Specified by:

resolveSchemaCompatibility in interface TypeSerializerSnapshot<SharedBuffer<V>>

Overrides:

resolveSchemaCompatibility in class TypeSerializerConfigSnapshot<SharedBuffer<V>>

Parameters:

newSerializer - the new serializer to check.

Returns:

the serializer compatibility result.
