@Deprecated
public class OptimisticCreateIfNotExistsInterceptor
extends OptimisticInterceptor

Used to create new NodeSPI instances in the main data structure and then copy it into the TransactionWorkspace as WorkspaceNodes as needed. This is only invoked if nodes needed do not exist in the underlying structure, they are added and the corresponding WorkspaceNode.isCreated() would return true to denote that this node has been freshly created in the underlying structure.
