- public class KeyIterator
- extends LocPathIterator
This class implements an optimized iterator for
"key()" patterns. This iterator incrementally walks the
source tree and finds all the nodes that match
a given key name and match pattern.
This class is based on an implementation from the Apache XML
Project. In future releases the XML parser, XSLT processor, and
associated classes will likely be updated to be based on a later
version of the Apache implementations. Since Apache does not guarantee
backwards compatibility between versions of their software, we cannot
guarantee backwards compatibility of any of the classes contained in
the weblogic.apache package or sub-packages.

KeyIterator
public KeyIterator(org.w3c.dom.Node doc,
PrefixResolver nscontext,
QName name,
java.util.Vector keyDeclarations,
XPathContext xctxt)
- Constructor KeyIterator
- Parameters:
doc
- The document nodenscontext
- The prefix resolver for the execution context.name
- The key namekeyDeclarations
- The key declarations from the stylesheetxctxt
- The XPath runtime state
getName
public QName getName()
- Get the key name from a key declaration this iterator will process
- Returns:
- Key name
getKeyDeclarations
public java.util.Vector getKeyDeclarations()
- Get the key declarations from the stylesheet
- Returns:
- Vector containing the key declarations from the stylesheet
nextNode
public org.w3c.dom.Node nextNode()
throws org.w3c.dom.DOMException
- Returns the next node in the set and advances the position of the
iterator in the set. After a NodeIterator is created, the first call
to nextNode() returns the first node in the set.
- Returns:
- The next
Node
in the set being iterated over, or
null
if there are no more members in that set. - Throws:
- org.w3c.dom.DOMException -
- Overrides:
- nextNode in class LocPathIterator
setLookupKey
public void setLookupKey(java.lang.String lookupKey)
- Set the value of the key that this iterator will look for
- Parameters:
lookupKey
- value of the key to look for
