Method Detail

setStartNode

public DTMAxisIterator setStartNode(int node)

Override the value of _node only when this object was constructed using the empty constructor.

Parameters:

node - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

reset

public DTMAxisIterator reset()

Description copied from interface: DTMAxisIterator

Resets the iterator to the last start node.

Specified by:

reset in interface DTMAxisIterator

Overrides:

reset in class DTMAxisIteratorBase

Returns:

A DTMAxisIterator which has been reset to the start node, which may or may not be the same as this iterator.

next

public int next()

Description copied from interface: DTMAxisIterator

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

setMark

public void setMark()

Description copied from interface: DTMAxisIterator

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

gotoMark

public void gotoMark()

Description copied from interface: DTMAxisIterator

Restores the current node remembered by setMark().
