- public class AttributeIterator
- extends LocPathIterator
This class implements an optimized iterator for
attribute axes patterns.
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.

AttributeIterator
public AttributeIterator(Compiler compiler,
int opPos,
int analysis)
throws javax.xml.transform.TransformerException
- Create a AttributeIterator object.
- Parameters:
compiler
- A reference to the Compiler that contains the op map.opPos
- The position within the op map, which contains the
location path expression for this itterator.- Throws:
- javax.xml.transform.TransformerException -
clone
public java.lang.Object clone()
throws java.lang.CloneNotSupportedException
- Get a cloned LocPathIterator that holds the same
position as this iterator.
- Returns:
- A clone of this iterator that holds the same node position.
- Throws:
- java.lang.CloneNotSupportedException -
- Overrides:
- clone in class LocPathIterator
cloneWithReset
public org.w3c.dom.traversal.NodeIterator cloneWithReset()
throws java.lang.CloneNotSupportedException
- Get a cloned Iterator that is reset to the beginning
of the query.
- Returns:
- A cloned NodeIterator set of the start of the query.
- Throws:
- java.lang.CloneNotSupportedException -
- Overrides:
- cloneWithReset in class LocPathIterator
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 - INVALID_STATE_ERR: Raised if this method is called after the
detach
method was invoked. - Overrides:
- nextNode in class LocPathIterator
getLastPos
public int getLastPos(XPathContext xctxt)
- Get the index of the last node that can be itterated to.
- Parameters:
xctxt
- XPath runtime context.- Returns:
- the index of the last node that can be itterated to.
- Overrides:
- getLastPos in class LocPathIterator
