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 .
