        uri - (the second argument of put())
        originator - the originating put() expression, for diagnostics
      • apply

        public void apply​(XPathContext context,
                          int validationMode)
                   throws XPathException
        Apply the pending updates
        Specified by:
        apply in interface PendingUpdateList
        context - the XPath dynamic evaluation context
        validationMode - the revalidation mode from the static context
        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:
        getAffectedTrees in interface PendingUpdateList
        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.
