first

public int first(int context,
                 int expandedTypeID)

Return the root if it matches the expanded type ID, else return null (nothing found)

Overrides:

first in class DTMDefaultBaseTraversers.AllFromRootTraverser

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.

Overrides:

next in class DTMDefaultBaseTraversers.AllFromRootTraverser

Parameters:

context - The context node of this iteration.

current - The current node of the iteration.

Returns:

Always return NULL for this axis.

                int current,
                int expandedTypeID)

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

Overrides:

next in class DTMDefaultBaseTraversers.AllFromRootTraverser

Parameters:

context - The context node of this iteration.

current - The current node of the iteration.
