Method Detail

withRootRevision

public DocumentNodeState withRootRevision(@NotNull
                                          @NotNull RevisionVector root,
                                          boolean externalChange)

Creates a copy of this DocumentNodeState with the rootRevision 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 fromExternalChange flags are equal.

Specified by:

withRootRevision in class AbstractDocumentNodeState

Parameters:

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

externalChange - if the fromExternalChange 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.

fromExternalChange

@NotNull
public @NotNull DocumentNodeState fromExternalChange()

Returns:

a copy of this DocumentNodeState with the fromExternalChange flag set to true.

isFromExternalChange

public boolean isFromExternalChange()

Specified by:

isFromExternalChange in class AbstractDocumentNodeState

Returns:

true if this node state was created as a result of an external change; false otherwise.

getRootRevision

@NotNull
public @NotNull RevisionVector getRootRevision()

Returns the root revision for this node state. This is the root revision passed from the parent node state. This revision therefore reflects the revision of the root node state where the traversal down the tree started.

Specified by:

getRootRevision in class AbstractDocumentNodeState

Returns:

the revision of the root node state.
