POPython customized Exception class should allow to continue the program execution after it has been raised
text
Body
copied!<p>I wrote a Python programm that has a customized Exception class called TAException and it works fine. But a new requirement forces me to extend its functionaliy. If the user sets a specific flag (-n) on program startup the program should NOT stop execution if TAException is raised.</p> <p>Below you see how I tried to implement it. In main() TAException.setNoAbort() gets called if that flag has been set. The rest is maybe self-explaining. The point is: Obviously it doesn't work. The program always aborts when TAException is raised. I know why it doesn't work, but I do not know how I can implement it differently. Could you please show me an elegant way to do this?</p> <pre><code>class TAException(Exception): _numOfException = 0 # How often has this exception been raised? _noAbort = False # By default we abort the test run if this exception has been raised. def __init__(self, TR_Inst, expr, msg): ''' Parameters: TR_Inst: Testreport instance expr: Expression in which the error occured. msg: Explanation for the error. ''' if TR_Inst != None: if TAException._noAbort is True: # If we abort the test run on the first exception being raised. TAException._numOfException += 1 # Or else only count the exception and continue the test run. # The status of the testreport will be set to "Failed" by TestReportgen. else: TR_Inst.genreport([expr, msg], False) # Generate testreport and exit. @staticmethod def setNoAbort(): ''' Sets TAException._noAbort to True. ''' TAException._noAbort = True </code></pre>
