		0 ignored issues – show Duplication introduced 2016-06-24 22:28 UTC by Report Bug Copy Issue Report This class seems to be duplicated in your project. Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...
