Constructor Details

QueryIteratorMapped

public QueryIteratorMapped(QueryIterator qIter,
 Map<Var,Var> varMapping)

Creates a new iterator

If the varMapping is null then no variable re-mapping will be applied and this will act as a simple wrapper over the underlying wrapper

Parameters:

qIter - Iterator to wrap

varMapping - Variable mapping
