Instance Method Details

#optimizable? ⇒ Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Test if the left operand is redundant

Returns:

• (Boolean)

def optimizable?
  operation.kind_of?(left.class) && right.eql?(left.right)
end

#optimize ⇒ Function
