public void apply(XPathContext context, int validationMode) throws XPathException
Apply the pending updates- Specified by:
applyin interfacePendingUpdateList- Parameters:
context- the XPath dynamic evaluation contextvalidationMode- the revalidation mode from the static context- Throws:
XPathException- if the operation fails
-
getAffectedTrees
public java.util.Set<MutableNodeInfo> getAffectedTrees()
Get the root nodes of the trees that are affected by updates in the pending update list- Specified by:
getAffectedTreesin interfacePendingUpdateList- Returns:
- the root nodes of affected trees, as a Set. Note that this includes all trees that have been updated; this is a superset of the trees that need to be revalidated, but updates that don't require revalidation are sufficiently unusual that we don't trouble with the distinction.
