ChildTestIterator
public ChildTestIterator(Compiler compiler,
int opPos,
int analysis)
throws javax.xml.transform.TransformerException
- Create a ChildTestIterator 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 -
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
