Constructor Detail


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

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


public void apply(XPathContext context,
                  Set affectedRootSet)
Apply the pending update action to the affected nodes

Specified by:
apply in class PendingUpdateAction
context - the XPath evaluation context
affectedRootSet - the set of roots of trees that have been modified, which this action should add to as necessary
XPathException - if any error occurs applying the update


public NodeInfo getTargetNode()
Get the target node of the update action

Specified by:
getTargetNode in class PendingUpdateAction
the target node, the node to which this update action applies. Returns null in the case of a delete action, which affects multiple nodes.


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