Detailed Description
An iterator over values a switch variable can take.
This iterator is intended to provide the start value for emulation of a jump-table model to obtain the associated jump-table destination. Each value can be associated with a starting Varnode and PcodeOp in the function being emulated, via getStartVarnode() and getStartOp().
