			0 ignored issues – show Documentation introduced 2015-12-16 14:17 UTC by Report Bug Copy Issue Report For interfaces and abstract methods it is generally a good practice to add a `@return` annotation even if it is just `@return void` or `@return null`, so that implementors know what to do in the overridden method. For interface and abstract methods, it is impossible to infer the return type from the immediate code. In these cases, it is generally advisible to explicitly annotate these methods with a `@return` doc comment to communicate to implementors of these methods what they are expected to return.
