Example 2 with TypeGeneric

the class IntrospectionUtils method getMethodReturnAttributesType.

/**

 * {@code method}.

 * If the {@code method} returns a {@link Result}, then it returns the type of the {@code Attributes} generic. In any other case
 * (including raw uses of {@link Result}) it will return a {@link VoidType}
 * <p>
 * If the {@code method} returns a collection or a {@link PagingProvider} of {@link Result}, then this will return
 * {@link VoidType} since the messages in the main output already contain an attributes for each item.
 *
 * @param method the {@link Method} being introspected
 * @return a {@link MetadataType}
 * @throws IllegalArgumentException is method is {@code null}
