Constructor Detail

SAX2DTM2.AncestorIterator

public SAX2DTM2.AncestorIterator()

Method Detail

getStartNode

public int getStartNode()

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

Specified by:

getStartNode in interface DTMAxisIterator

Overrides:

getStartNode in class DTMAxisIteratorBase

Returns:

The root node of the iteration.

isReverse

public final boolean isReverse()

True if this iterator has a reversed axis.

Specified by:

isReverse in interface DTMAxisIterator

Overrides:

isReverse in class DTMAxisIteratorBase

Returns:

true since this iterator is a reversed axis.

cloneIterator

public DTMAxisIterator cloneIterator()

Returns a deep copy of this iterator. The cloned iterator is not reset.

Specified by:

cloneIterator in interface DTMAxisIterator

Overrides:

cloneIterator in class DTMAxisIteratorBase

Returns:

a deep copy of this iterator.

setStartNode

public DTMAxisIterator setStartNode(int node)

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

Parameters:

node - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

reset

public DTMAxisIterator reset()

Resets the iterator to the last start node.

Specified by:

reset in interface DTMAxisIterator

Overrides:

reset in class DTMAxisIteratorBase

Returns:

A DTMAxisIterator, which may or may not be the same as this iterator.

next

public int next()

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

setMark

public void setMark()

Description copied from class: DTMDefaultBaseIterators.InternalAxisIteratorBase

Remembers the current node for the next call to gotoMark(). %REVIEW% Should this save _position too?

Specified by:

setMark in interface DTMAxisIterator

Overrides:

setMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase

gotoMark

public void gotoMark()

Description copied from class: DTMDefaultBaseIterators.InternalAxisIteratorBase

Restores the current node remembered by setMark(). %REVEIW% Should this restore _position too?

Specified by:

gotoMark in interface DTMAxisIterator

Overrides:

gotoMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase
