Annotation Interface PermazenSetField

@Retention(RUNTIME) @Target({ANNOTATION_TYPE,METHOD}) @Documented public @interface PermazenSetField
Java annotation for the getter methods of Java bean properties reflecting Permazen Set fields.

The annotated method's return type must be either Set<E>, SortedSet<E>, or NavigableSet<E>, where E is a supported simple type.

Note that both primitive types and their corresponding wrapper types are supported as elements. A set whose elements have primitive type will throw an exception on an attempt to add a null value. To specify a primitive element type, specify the primitive type name (e.g., "int") as the PermazenField.encoding() in the element().
