Package org.apache.xalan.transformer
Class KeyIterator
- All Implemented Interfaces:
Serializable,Cloneable,SourceLocator,DTMIterator,PathComponent,SubContextList,ExpressionNode,XPathVisitable
This class implements an optimized iterator for
"key()" patterns, matching each node to the
match attribute in one or more xsl:key declarations.

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:
acceptNodein 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 .
