getTypeParameters

protected abstract Type[] getTypeParameters(TypeReifier r,
                                            T object)

Returns a Type array, where the ith Type in the array is the ith type parameter of the Class returned by TypeExtractor.baseClass(). Similar to ParameterizedType.getActualTypeArguments(), but works on Objects instead of ParameterizedTypes.

Parameters:

r - the TypeReifier used to reify the type parameters.

object - the Object to extract type parameters from.

Returns:

the actual type arguments of Object, with respect to the Type returned by TypeExtractor.baseClass()

                  Object object)
