Constructor Detail

WalkingIteratorSorted

public WalkingIteratorSorted(PrefixResolver nscontext)
Create a WalkingIteratorSorted object.
Parameters:
nscontext - The namespace context for this iterator, should be OK if null.
Method Detail

isDocOrdered

public boolean isDocOrdered()
Returns true if all the nodes in the iteration well be returned in document order.
Returns:
true as a default.
Overrides:
isDocOrdered in class LocPathIterator

fixupVariables

public void fixupVariables(java.util.Vector vars,
                           int globalsSize)
This function is used to perform some extra analysis of the iterator.
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).
Overrides:
