public abstract class TrackableContext<CtxT extends TrackableContext<CtxT>>
extends InjectionContext

An InjectionContext that can execute tasks within itself, so that it can be tracked across threads using the associated ContextTracker.

Overriding classes must use themselves as CtxT type argument.
