WalkingIteratorSorted

WalkingIteratorSorted(Compiler compiler,
 int opPos,
 int analysis)
               throws TransformerException

Create a WalkingIterator iterator, including creation of step walkers from the opcode list, and call back into the Compiler to create predicate expressions.

Parameters:

compiler - The Compiler which is creating this expression.

opPos - The position of this iterator in the opcode list from the compiler.

Throws:

TransformerException - if any
