| * Identifies 0..n public methods to check preconditions for the integration to work. These are the rules: | ||
| * | ||
| * <ul> | ||
| * <li>Both the type and the method(s) must be annotated with {@code @CheckAvailability}</li> | ||
| * <li>Only public no-arg boolean methods are considered</li> | ||
| * <li>Methods <em>may</em> be {@code static}, in which case they get invoked before instantiating the service</li> | ||
| * <li>Should the method throw an exception, it has the same effect as returning {@code false}</li> | ||
| * <li>No specific execution order is guaranteed in case of multiple annotated methods</li> | ||
| * <li>Annotations must be present on classes or ancestor classes, not on interfaces</li> | ||
| * </ul> | ||
| * | ||
| * Example: | ||
| * <pre> | ||
| * {@code | ||
| * @CheckAvailability | ||
| * public class Foo { | ||
| * @CheckAvailability | ||
| * public static boolean isSupported() { | ||
| * return "enabled".equals(System.getProperty("plugin.status")); | ||
| * } | ||
| * } | ||
| * } | ||
| * </pre> | ||
| * <p> | ||
| * Annotations are discovered at runtime using reflection, so make sure to make relevant classes accessible to this | ||
| * module ({@code opens X to org.cryptomator.integrations.api}). | ||

| * @since 1.1.0 | ||
