```
public abstract class SignatureVisitor
extends Object
```
A visitor to visit a generic signature. The methods of this interface must be called in one of the three following orders (the last one is the only valid order for a SignatureVisitor that is returned by a method of this interface):
- ClassSignature = ( visitFormalTypeParameter visitClassBound? visitInterfaceBound* )* ( visitSuperClass visitInterface* )
- MethodSignature = ( visitFormalTypeParameter visitClassBound? visitInterfaceBound* )* ( visitParameterType* visitReturnType visitExceptionType* )
- TypeSignature = visitBaseType | visitTypeVariable | visitArrayType | ( visitClassType visitTypeArgument* ( visitInnerClassType visitTypeArgument* )* visitEnd ) )
