Method Details

getNextNode

protected int getNextNode()

Get the next node via getNextXXX. Bottlenecked for derived class override.

Overrides:

getNextNode in class ChildTestIterator

Returns:

The next node on the axis, or DTM.NULL.

getAxis

public int getAxis()

Returns the axis being iterated, if it is known.

Specified by:

getAxis in interface DTMIterator

Overrides:

getAxis in class ChildTestIterator

Returns:

Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.
