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.- Specified by:
isDocOrdered
in interfaceDTMIterator
- Overrides:
isDocOrdered
in classLocPathIterator
- Returns:
- true as a default.
-
fixupVariables
public void fixupVariables(java.util.Vector vars, int globalsSize)
This function is used to perform some extra analysis of the iterator.- Overrides:
fixupVariables
in classWalkingIterator
- 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).
