All Implemented Interfaces:

org.apache.jackrabbit.oak.spi.state.NodeState

public class DelegatingDocumentNodeState
extends AbstractDocumentNodeState

NodeState wrapper which wraps another NodeState (mostly SegmentNodeState) so as to expose it as an AbstractDocumentNodeState by extracting the meta properties which are stored as hidden properties

Wraps a given root NodeState as a DelegatingDocumentNodeState if it has required meta properties otherwise just returns the passed NodeState

Parameters:

delegate - nodeState to wrap

Returns:

wrapped state or original state

Description copied from class: AbstractDocumentNodeState

Creates a copy of this DocumentNodeState with the AbstractDocumentNodeState.getRootRevision() set to the given root revision. This method returns this instance if the given root revision is the same as the one in this instance and the AbstractDocumentNodeState.isFromExternalChange() flags are equal.

Specified by:

withRootRevision in class AbstractDocumentNodeState

Parameters:

root - the root revision for the copy of this node state.

externalChange - if the AbstractDocumentNodeState.isFromExternalChange() flag must be set on the returned node state.

Returns:

a copy of this node state with the given root revision and external change flag.
