'''SplitTemporaryVariable''': ''"You have a temporary variable assigned to more than once, but it is not a loop variable or a collecting temporary variable. -> Make a separate temporary variable for each assignment."'' From page 128 of RefactoringImprovingTheDesignOfExistingCode book: http://www.refactoring.com/catalog/splitTemporaryVariable.html ----- Typical symptom: A single variable has different meanings in different parts of a method. Conclusion: 1. The method is too long. 2. You need two variables; one for each usage. ---- See: the "paint_required" example at the bottom of ConstCorrectness.
