package sun.reflect.generics.repository;
This class represents the generic type information for a constructor. 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 genericType// caches the generic type info
 // protected, to enforce use of static factory yet allow subclassing
    protected FieldRepository(String rawSigGenericsFactory f) {
      super(rawSigf);
    }
    protected TypeSignature parse(String s) {
        return SignatureParser.make().parseTypeSig(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 FieldRepository that manages the generic type information represented in the signature rawSig
    public static FieldRepository make(String rawSig,
                                             GenericsFactory f) {
        return new FieldRepository(rawSigf);

 * If not, it is created lazily. This is done by selecting the appropriate
