package com.fasterxml.jackson.databind.annotation;

 * Marker class used with annotations to indicate "no class". This is
 * a silly but necessary work-around -- annotations cannot take nulls
 * as either default or explicit values. Hence for class values we must
 * explicitly use a bogus placeholder to denote equivalent of
 * "no class" (for which 'null' is usually the natural choice).
 * Note that since 2.4, most (but not all!
 * {@link com.fasterxml.jackson.annotation.JsonTypeInfo#defaultImpl} is
 * a notable exception}) usage should start using
 * {@link java.lang.Void} instead as the "not defined" marker.
public final class NoClass
    private NoClass() { }
