  Class | Description
  --- | ---
  ApiStatus | Set of annotations which can be used to specify status of API Element.
  ApiStatus.AvailableSince | Indicates that the annotated element firstly appeared in the specified version of the library, so the code using that element won't be compatible with older versions of the library.
  ApiStatus.Experimental | Indicates that a public API of the annotated element (class, method or field) is not in stable state yet.
  ApiStatus.Internal | Indicates that the annotated element (class, method, field, etc) must not be considered as a public API.
  ApiStatus.NonExtendable | Indicates that the annotated API class, interface or method must not be extended, implemented or overridden.
  ApiStatus.OverrideOnly | Indicates that the annotated method is part of SPI (Service Provider Interface), which is intended to be only implemented or overridden but not called by clients of the declaring library.
  ApiStatus.ScheduledForRemoval | Indicates that a public API of the annotated element (class, method or field) is subject to removal in a future version.
  Async | Helper annotations for asynchronous computation.
  Async.Execute | Indicates that the marked method executes async computation.
  Async.Schedule | Indicates that the marked method schedules async computation.
  Contract | Specifies some aspects of the method behavior depending on the arguments.
  Debug |
  Debug.Renderer | Allows to change the presentation of an object in debuggers
  Flow | This annotation assists the 'Data flow to this' feature by describing data flow from the method parameter to the corresponding container (e.g.

  Language | Specifies that an element of the program represents a string that is a source code on a specified language.
  MagicConstant | This annotation intended to help IntelliJ IDEA and other IDEs to detect and auto-complete int and String constants used as an enumeration.
  Nls | Specifies that an element of the program is an user-visible string which needs to be localized.
  Nls.Capitalization |
  NonNls | Specifies that an element of the program is not an user-visible string which needs to be localized, or does not contain such strings.
  NotNull | An element annotated with NotNull claims `null` value is forbidden to return (for methods), pass to (parameters) and hold (local variables and fields).
  Nullable | An element annotated with `Nullable` claims `null` value is perfectly valid to return (for methods), pass to (parameters) or hold in (local variables and fields).
  Pattern | Specifies that an element of the program represents a string that must completely match given regular expression.
  PrintFormat |
  PropertyKey | Specifies that a method parameter accepts arguments which must be valid property keys in a specific resource bundle.
  Range | An annotation which allows to specify for integral type (byte, char, short, int, long) an allowed values range.
  RegExp | Specifies that an element of the program represents a string that is a regular expression text supported by `Pattern`.
  Subst |
  TestOnly | A method/constructor annotated with TestOnly claims that it should be called from testing code only.
  Unmodifiable | An annotation which marks a `Collection` or `Map` type as unmodifiable.
  UnmodifiableView | An annotation which marks a `Collection` or `Map` type as unmodifiable view.
