Static factory method.
Params:
  • 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 MethodRepository that manages the generic type information represented in the signature rawSig
