RenameAction

public RenameAction(NodeInfo node,
            NodeName newName)

Create a RenameAction

Parameters:

node - the node to be renamed

newName - the new name

Method Detail

apply

public void apply(XPathContext context,
         Set affectedRootSet)

Apply the pending update action to the affected nodes

Specified by:

apply in class PendingUpdateAction

Parameters:

context - the XPath evaluation context

affectedRootSet - the set of roots of trees that have been modified, which this action should add to as necessary

getTargetNode

public NodeInfo getTargetNode()

Get the target node of the update action

Specified by:

getTargetNode in class PendingUpdateAction

Returns:

the target node, the node to which this update action applies. Returns null in the case of a delete action, which affects multiple nodes.

getNewName

public NodeName getNewName()

Get the new name as an integer namecode

Returns:

the new name as an integer namecode

getApplyPhase

public int getApplyPhase()

Get the phase of operation in which this pending update action is applied. See 3.2.2 upd:applyUpdates, Semantics, rule 2. However, the spec does rename, and insert as a single phase; we split it so that rename is phase 0, while insert is phase 1. This ensures that old attributes are renamed before new attributes are inserted, avoiding spurious conflicts.

Specified by:

getApplyPhase in class PendingUpdateAction

Returns:

the phase of operation, an integer in the range 1 to 5 representing the stages labelled a-e in the specification
