Class Wildcard

Direct Known Subclasses:

public abstract class Wildcard

extends java.lang.Object

Interface Wildcard is a placeholder for serveral classes or class lists at a time.

All classes implementing wildcard will have to provide a default constructor!

This is the expected way to use wildcards: if yourwildcard extends Wildcard, then ask your wildcard whether it is assignable from something else using:

 yourwildcard.newInstance().isAssignableFrom(String.class)
