Split Temporary Variable

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.
