24/**
25 * Use this to meta-annotate XxxFeature.Require annotations, so that those
26 * annotations can be used to decide whether to apply a test to a given
27 * class-under-test.
28 * <br>
29 * This is needed because annotations can't implement interfaces, which is also
30 * why reflection is used to extract values from the properties of the various
31 * annotations.
32 *
33 * <p>This class is GWT compatible.
