Class TemporaryLocalReplacementVariable

java.lang.Object

org.jruby.ir.operands.Operand

org.jruby.ir.operands.Variable

org.jruby.ir.operands.TemporaryVariable

org.jruby.ir.operands.TemporaryLocalVariable

org.jruby.ir.operands.TemporaryLocalReplacementVariable

All Implemented Interfaces:

java.lang.Comparable, DepthCloneable

public class TemporaryLocalReplacementVariable
extends TemporaryLocalVariable
implements DepthCloneable

When we optimize full local variables to be temporary ones we like to keep the name of what we renamed them as. This is just enough wrapper for us to maintain a nice debug string.
