Annotation Types Summary
Annotation Type	Description
Cache	An annotation for an instance variable that caches a value.
Configured	An annotation for instance variables in reusable objects that are configured dynamically but are not reassigned until the object is reconfigured.
CreatedOnDemand	An annotation for instance variables that are created on demand (and thus never reveal themselves as null to the outside world).
Fixed	A variable or method result is fixed if it always has the same value.
Immutable	An annotation for classes whose instances are immutable.
InvokedUsingReflection	An annotation for constructors and methods that are invoked using reflection.
NoInstances	An annotation for a class that only defines static members (no instantiation).
NotNullUntilReleased	An annotation for instance variables that nullified only when the containing object is released.
SingleInstance	An annotation for a class that has a unique instance.
Uninitialized	An annotation for method and constructor parameters that must not be invoked because they are not fully initialized.
Value	An annotation for classes expected to become value classes.
Volatile	An annotation for method parameters or results that must not be retained (because they may be reused).
