| Method Summary | |
| public int | asNode(XPathContext xctxt)
Return the first node out of the nodeset, if this expression is
a nodeset expression. | | public DTMIterator | cloneWithReset()
Get a cloned Iterator that is reset to the beginning
of the query. | | public boolean | deepEquals(Expression expr)
| | public void | detach()
Detaches the iterator from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state. | | public int | getAxis()
Returns the axis being iterated, if it is known. | | public int | nextNode()
Returns the next node in the set and advances the position of the
iterator in the set. | | public void | setRoot(int context, Object environment)
Initialize the context values for this expression
after it is cloned. |
| m_axis | | protected int m_axis(Code) | | The axis that we are traversing.
|
| m_extendedTypeID | | protected int m_extendedTypeID(Code) | | The extended type ID, not set until setRoot.
|
| m_traverser | | protected transient DTMAxisTraverser m_traverser(Code) | | The traverser to use to navigate over the descendants.
|
| serialVersionUID | | final static long serialVersionUID(Code) | | |
| DescendantIterator | | public DescendantIterator()(Code) | | Create a DescendantIterator object.
|
| asNode | | public int asNode(XPathContext xctxt) throws javax.xml.transform.TransformerException(Code) | | Return the first node out of the nodeset, if this expression is
a nodeset expression. This is the default implementation for
nodesets.
WARNING: Do not mutate this class from this function!
Parameters:
xctxt - The XPath runtime context. the first node out of the nodeset, or DTM.NULL. |
| detach | | public void detach()(Code) | | Detaches the iterator from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state. Afterdetach has been invoked, calls to
nextNode orpreviousNode will raise the
exception INVALID_STATE_ERR.
|
| getAxis | | public int getAxis()(Code) | | Returns the axis being iterated, if it is known.
Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types. |
| nextNode | | public int nextNode()(Code) | | 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.
The next Node in the set being iterated over, ornull if there are no more members in that set.
throws:
DOMException - INVALID_STATE_ERR: Raised if this method is called after thedetach method was invoked. |
| setRoot | | public void setRoot(int context, Object environment)(Code) | | Initialize the context values for this expression
after it is cloned.
Parameters:
context - The XPath runtime context for thistransformation. |
