Suspicious Contents – The Daily WTF

Programming LanguageSuspicious Contents - The Daily WTF


While poring through some VB .Net code, John noticed some odd things in their datamodel. For example, a different process would scan files, and log any “suspicious” files into a database. The program John supported would then report on that data.

One of their classes had a property which looked like this:

Public ReadOnly Property SuspectedItem As SuspectFileDataItem
    Get
        Return Me
    End Get
End Property

Now, there are many reasons why a method might return a reference to the instance- builder patterns are often a nice way to describe things in code. But a property returning its own instance, well… that doesn’t make sense at all. “Give me the thing I already have.”

It didn’t help that it was also used: item.SuspectedItem.someProperty() was scattered all through the codebase.

Then again, perhaps this code is self describing. I suspect a lot of things about this item. I also have some suspicions about what substances this developer may or may not consume which lead to this code.
