/**
|
||
|
|
* If the annotation {@code @Documented} is present on the declaration
|
||
|
|
* of an annotation interface <i>A</i>, then any {@code @A} annotation on
|
||
|
|
* an element is considered part of the element's public contract.
|
||
|
|
*
|
||
|
|
* In more detail, when an annotation interface <i>A</i> is annotated with
|
||
|
|
* {@code Documented}, the presence and value of <i>A</i> annotations
|
||
|
|
* are a part of the public contract of the elements <i>A</i>
|
||
|
|
* annotates.
|
||
|
|
*
|
||
|
|
* Conversely, if an annotation interface <i>B</i> is <em>not</em>
|
||
|
|
* annotated with {@code Documented}, the presence and value of
|
||
|
|
* <i>B</i> annotations are <em>not</em> part of the public contract
|
||
|
|
* of the elements <i>B</i> annotates.
|
||
|
|
*
|
||
|
|
* Concretely, if an annotation interface is annotated with {@code Documented},
|
||
|
|
* by default a tool like javadoc will display annotations of that interface
|
||
|
|
* in its output while annotations of annotation interfaces without
|
||
|
|
* {@code Documented} will not be displayed.
