boolean	canCopyPropagate() Can we replace every use of a variable 'v' that contains the value of this operand with the operand itself? This takes importance when there are at least two uses of 'v' within this scope.

addUsedVariables

public void addUsedVariables(List<Variable> l)

Description copied from class: Operand

Append the list of variables used in this operand to the input list -- force every operand to implement this because a missing implementation can cause bad failures.

Specified by:

addUsedVariables in class Operand

canCopyPropagate

public boolean canCopyPropagate()

Description copied from class: Operand

Can we replace every use of a variable 'v' that contains the value of this operand with the operand itself? This takes importance when there are at least two uses of 'v' within this scope. Ex: v = [1,2,3]; x = v; y = v In this case, we cannot replace the occurences of 'v' because we would then get x = [1,2,3]; y = [1,2,3] which would then result in two different array objects being constructed instead of a single one.

Overrides:

canCopyPropagate in class Operand

Returns:

true if it is safe to copy-propagate the operand.

getSimplifiedOperand

public Operand getSimplifiedOperand(Map<Operand,Operand> valueMap,
                           boolean force)

Overrides:

toString

public String toString()

Overrides:

              IRubyObject self,
              DynamicScope currDynScope,
              Object[] temp)

Overrides:
