 package sun.reflect.generics.repository;
 
This class represents the generic type information for a class. The code is not dependent on a particular reflective implementation. It is designed to be used unchanged by at least core reflection and JDI.
 
 
     private Type superclass// caches the generic superclass info
     private Type[] superInterfaces// caches the generic superinterface info
 
  // private, to enforce use of static factory
     private ClassRepository(String rawSigGenericsFactory f) {
         super(rawSigf);
     }
 
     protected ClassSignature parse(String s) {
         return SignatureParser.make().parseClassSig(s);
     }

    
Static factory method.

Parameters:
rawSig - the generic signature of the reflective object that this repository is servicing
f - a factory that will provide instances of reflective objects when this repository converts its AST
Returns:
a ClassRepository that manages the generic type information represented in the signature rawSig
