    • 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 occurrences 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.
