toString

public String toString()

Overrides:

toString in class Object

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.

addUsedVariables

public void addUsedVariables(List<Variable> l)

Description copied from class: Operand
