Annotation Type Cached.Shared

@Retention(value=CLASS)
 @Target(value=PARAMETER)
public static @interface Cached.Shared

Allows sharing between multiple Cached parameters between multiple specializations or exported library messages. If no sharing is desired then the cached parameter can be annotated with exclusive. The DSL will indicate sharing opportunities to the user by showing a warning.

Shared caches with reference types must never return null for their initializer when they are used in guards, because the null value is reserved for the uninitialized state. An AssertionError will be thrown at runtime if that is the case. Shared caches with primitive types must not be used at all in guards.
