com.sun.jdi.ClassType
A mirror of a class in the target VM. A ClassType is a refinement of {@link ReferenceType} that applies to true classes in the JLSsense of the definition (not an interface, not an array type). Any {@link ObjectReference} that mirrors an instance of such a classwill have a ClassType as its type. @see ObjectReference @author Robert Field @author Gordon Hirsch @author James McIlree @since 1.3
