Constructor Detail

InsertAction

public InsertAction(NodeInfo[] content,
            MutableNodeInfo targetNode,
            int position,
            boolean inherit)

Create an InsertAction

Parameters:

content - the content sequence to be inserted (a value which must consist entirely of nodes. The caller is responsible for copying the nodes into the same object model representation as the tree into which they will be inserted; also for merging adjacent text nodes, extracting the children of a document node, and so on.)

targetNode - the node that defines where the new nodes will be inserted

position - defines where the nodes will be inserted: before or after the target node, or as the first or last child of the target node.

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

Throws:

XPathException - if any error occurs applying the update

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.

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.

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
