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.
