/**
|
|
* Generates classes that create annotation instances for an unwrapped {@link MapKey} annotation
|
|
* type whose nested value is an annotation. The generated class will have a private empty
|
|
* constructor and a static method that creates each annotation type that is nested in the top-level
|
|
* annotation type.
|
|
*
|
|
* <p>So for an example {@link MapKey} annotation:
|
|
*
|
|
* <pre>
|
|
* {@literal @MapKey}(unwrapValue = true)
|
|
* {@literal @interface} Foo {
|
|
* Bar bar();
|
|
* }
|
|
*
|
|
* {@literal @interface} Bar {
|
|
* {@literal Class<?> baz();}
|
|
* }
|
|
* </pre>
|
|
*
|
|
* the generated class will look like:
|
|
*
|
|
* <pre>
|
|
* public final class FooCreator {
|
|
* private FooCreator() {}
|
|
*
|
|
* public static Bar createBar({@literal Class<?> baz}) { … }
|
|
* }
|
|
* </pre>
