```
public JClassType[] getSubtypes()
```
    Description copied from class: JClassType
    Returns all subtypes for this type. This means various things:
    1. Array: subtypes are those array types with the same number of dimensions as this type, and whose base element type is a subtype of this type's element type.
    2. Wildcards: if ? extends X, subtypes are subtypes of X. If ? super X: no subtypes.
    3. Named type parameter: subtypes are (1) those subtypes of the "base" type that are assignable to this, plus (2) the first bound of the parameter, if the bound is both assignable to this and not an interface. The "base" is the type itself, except for delegating types, where the base is the result of getBaseType().
    4. Real class: subtypes are those real classes that are subtypes of this class in the class hierarchy. Interfaces aren't subtypes of Object.
    5. Parameterized type: subtypes are those subtypes of the generic type of this type which can be parameterized with the right types so that they have this type as a supertype. The subtypes are parameterized as described, with minimal parameterization.
    6. Raw type: subtypes are the subtypes of the generic type of this type, as raw types if they themselves are generic.
