WalkingIteratorSorted
public WalkingIteratorSorted(PrefixResolver nscontext)
- Create a WalkingIteratorSorted object.
- Parameters:
nscontext
- The namespace context for this iterator,
should be OK if null.
isDocOrdered
public boolean isDocOrdered()
- Returns true if all the nodes in the iteration well be returned in document
order.
- Specified by:
isDocOrdered
in interface DTMIterator
- Overrides:
isDocOrdered
in class LocPathIterator
- Returns:
- true as a default.
fixupVariables
public void fixupVariables(Vector vars,
int globalsSize)
- This function is used to perform some extra analysis of the iterator.
- Overrides:
fixupVariables
in class WalkingIterator
- Parameters:
vars
- List of QNames that correspond to variables. This list
should be searched backwards for the first qualified name that
corresponds to the variable reference qname. The position of the
QName in the vector from the start of the vector will be its position
in the stack frame (but variables above the globalsTop value will need
to be offset to the current stack frame).
