extends DTMDefaultBaseTraversers.AncestorTraverser

Implements traversal of the Ancestor access, in reverse document order.

Constructor Summary

private

DTMDefaultBaseTraversers.AncestorOrSelfTraverser()

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.
int	first(int context, int expandedTypeID) By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop.
int	next(int context, int current) Traverse to the next node after the current node.
int	next(int context, int current, int expandedTypeID) Traverse to the next node after the current node that is matched by the expanded type ID.

Method Detail

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.

first

public int first(int context,
                 int expandedTypeID)

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. If the context node does not match the expanded type ID, this function will return false.

Overrides:

first in class DTMAxisTraverser

Parameters:

context - The context node of this traversal.

expandedTypeID - The expanded type ID that must match.

Returns:

the first node in the traversal.

next

public int next(int context,
                int current)

Traverse to the next node after the current node.

Specified by:

next in class DTMAxisTraverser

Parameters:

context - The context node if this iteration.

current - The current node of the iteration.

Returns:

the next node in the iteration, or DTM.NULL.

DTMAxisTraverser.first(int)

next

public int next(int context,
                int current,
                int expandedTypeID)

Traverse to the next node after the current node that is matched by the expanded type ID.

Specified by:

next in class DTMAxisTraverser

Parameters:

context - The context node of this iteration.

current - The current node of the iteration.

expandedTypeID - The expanded type ID that must match.

Returns:

the next node in the iteration, or DTM.NULL.
