AbstractClassWithoutAnyMethod

AbstractClassWithoutAnyMethod

If an abstract class does not provides any methods, it may be acting as a simple data container that is not meant to be instantiated. In this case, it is probably better to use a private or protected constructor in order to prevent instantiation than make the class misleadingly abstract.


                    
//ClassOrInterfaceDeclaration[
	(@Abstract = 'true')
	and
	(count(//MethodDeclaration) + count(//ConstructorDeclaration) = 0)
]
                    

Example(s):


            
public class abstract Example {
	String field;
	int otherField;
}
