supportsRelocationOfSerializedObjects Property
supportsRelocationOfSerializedObjects should be enabled (i.e. true) only when reordering the bytes of serialized objects in serialization stream output is equivalent to having re-ordered those elements prior to serializing them.
supportsRelocationOfSerializedObjects is disabled (i.e. false) by default.

Note

KryoSerializer uses autoReset for supportsRelocationOfSerializedObjects.
