Method Summary

Modifier and TypeMethod and Description
public DTMAxisIterator
cloneIterator()

Overrides com.sun.org.apache.xml.internal.dtm.ref.DTMAxisIteratorBase.cloneIterator.

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.cloneIterator.

Returns a deep copy of this iterator.

public int
getNode(int index)

public int
getNodeByPosition(int pos)

Overrides com.sun.org.apache.xml.internal.dtm.ref.DTMAxisIteratorBase.getNodeByPosition.

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.getNodeByPosition.

Return the node at the given position.

public int
getPosition()

Overrides com.sun.org.apache.xml.internal.dtm.ref.DTMAxisIteratorBase.getPosition.

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.getPosition.

public void
gotoMark()

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.gotoMark.

Restores the current node remembered by setMark().

public int
next()

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.next.

Get the next node in the iteration.

public DTMAxisIterator
reset()

Overrides com.sun.org.apache.xml.internal.dtm.ref.DTMAxisIteratorBase.reset.

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.reset.

Resets the iterator to the last start node.

public void
setMark()

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.setMark.

Remembers the current node for the next call to gotoMark().

public void
setRestartable(boolean isRestartable)

Overrides com.sun.org.apache.xml.internal.dtm.ref.DTMAxisIteratorBase.setRestartable.

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.setRestartable.

Set if restartable.

public DTMAxisIterator
setStartNode(int node)

Implements com.sun.org.apache.xml.internal.dtm.DTMAxisIterator.setStartNode.

Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.
