KeyRefIterator
public KeyRefIterator(QName name, XMLString ref, java.util.Vector keyDecls, DTMIterator ki)
Constructor KeyRefIterator- Parameters:
ref
- Key value to matchki
- The main key iterator used to walk the source tree
-
-
Method Detail
-
filterNode
public short filterNode(int testNode)
Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. This function will be called by the implementation of TreeWalker and NodeIterator; it is not intended to be called directly from user code.- Parameters:
testNode
- The node to check to see if it passes the filter or not.- Returns:
- a constant to determine whether the node is accepted, rejected, or skipped, as defined above .
