Annotation Types Summary
InjectableComponent The annotated type (a component), field (a component dependency for another class), or constructor was designed to be compatible with injection, meaning that: for Types, other classes can confidently access an instance of this type as a dependency via auto-wired injection; for Fields, they can be instantiated via auto-wired dependency injection; for Constructors, there are no parameters declared which are NonInjectableComponents, and thus should be satisfiable under default dependency injection circumstances
NonInjectableComponent The annotated type (a component), field (a component dependency for another class), or constructor was not designed to be compatible with injection, meaning that: for Types, other classes should not attempt to access an instance of this type as a dependency via auto-wired injection, as instances of this type retain instance-specific state; for Fields, they should be instantiated manually; for Constructors, the parameters declared in them include components which are NonInjectableComponents, and thus would not be satisfiable under default dependency injection circumstances
NotNull The annotated field, method result, parameter or local variable must not be null.
OnDemand Describes elements in JIRA code base, whose change will affect the On Demand code in terms of compilation or runtime behaviour.
