Constructor Summary

DTMDefaultBaseTraversers.DescendantOrSelfTraverser()

Method Summary

int	first(int context) By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop.
protected int	getFirstPotential(int identity) Get the first potential identity that can be returned, which is the axis context, in this case.

Method Detail

getFirstPotential

protected int getFirstPotential(int identity)

Get the first potential identity that can be returned, which is the axis context, in this case.

Overrides:

getFirstPotential in class DTMDefaultBaseTraversers.DescendantTraverser

Parameters:

identity - The node identity of the root context of the traversal.

Returns:

The axis context.

first

public int first(int context)

By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop. To see if the self node should be processed, use this function.

Overrides:

first in class DTMAxisTraverser

Parameters:

context - The context node of this traversal.

Returns:

the first node in the traversal.
