Hi,
Is it possible to override plus equals (+=) for a class?
I have a class the is want plus to be immutable and plusEquals to be
mutable e.g:
def newMatrix = myMatrix + additionalRows
assert myObj == myMatrix - additionalRows
myMatrix += additionalRows
assert myMatrix == newMatrix
Since my implementation of plus involves cloning myMatrix which in my
case is expensive, it would be a big difference if I could avoid that
when there is no need. However += is calling plus and then assigning
the result under the covers. Is there a way to "get to it" to override?
Best regards,
Per
