Create a SelfIteratorNoPredicate object.
Params:
  • 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.
  • analysis – Analysis bits.
Throws:
/** * Create a SelfIteratorNoPredicate object. * * @param compiler A reference to the Compiler that contains the op map. * @param opPos The position within the op map, which contains the * location path expression for this itterator. * @param analysis Analysis bits. * * @throws javax.xml.transform.TransformerException */

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.

Return the first node out of the nodeset, if this expression is a nodeset expression. This is the default implementation for nodesets. Derived classes should try and override this and return a value without having to do a clone operation.
Params:
  • xctxt – The XPath runtime context.
Returns:the first node out of the nodeset, or DTM.NULL.
