modifyResultOperation

protected JExpression modifyResultOperation(JBinaryOperation op)

Description copied from class: CompoundAssignmentNormalizer

Decide what expression to return when breaking up a compound assignment of the form lhs op= rhs. The breakup creates an expression of the form lhs = lhs op rhs, and the right hand side of the newly created expression is passed to this method.
