Class RawSignature

java.lang.Object
randoop.reflection.RawSignature
public class RawSignature extends Object
Represents the raw type signature for an java.lang.reflect.AccessibleObject. This signature consists of the classname as a fully-qualified raw type, the method name, and the argument types as fully-qualified raw types. It does not include the method or constructor name.

The raw type signature for a constructor C() is C() instead of the reflection form C.<init>(). Also, the name and the classname of a constructor are the same.
