Constructor Detail

• SelfIteratorNoPredicate

  public SelfIteratorNoPredicate()
                          throws javax.xml.transform.TransformerException

  Create a SelfIteratorNoPredicate object.

  Throws:

  javax.xml.transform.TransformerException

Method Detail

• nextNode

  public int nextNode()

  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.

  Specified by:

  nextNode in interface DTMIterator

  Specified by:

  nextNode in class LocPathIterator

  Returns:

  The next Node in the set being iterated over, or null if there are no more members in that set.

• asNode

  public int asNode​(XPathContext xctxt)
             throws javax.xml.transform.TransformerException

  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.

  Overrides:

  asNode in class LocPathIterator

  Parameters:

  xctxt - The XPath runtime context.

  Returns:

  the first node out of the nodeset, or DTM.NULL.

  Throws:

  javax.xml.transform.TransformerException

• getLastPos

  public int getLastPos​(XPathContext xctxt)

  Get the index of the last node that can be itterated to. This probably will need to be overridded by derived classes.

  Specified by:

  getLastPos in interface SubContextList

  Overrides:

  getLastPos in class LocPathIterator

  Parameters:

  xctxt - XPath runtime context.

  Returns:

  the index of the last node that can be itterated to.
