Method Details
-
getName
Get the key name from a key declaration this iterator will process- Returns:
- Key name
-
getKeyDeclarations
Get the key declarations from the stylesheet- Returns:
- Vector containing the key declarations from the stylesheet
-
acceptNode
public short acceptNode(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.- Overrides:
acceptNode
in classPredicatedNodeTest
- 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 .
