/**
 * 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() { } }
