ContextScope (Guice Context Scopes 9.2 API)

java.lang.Object
- pl.morgwai.base.guice.scopes.ContextScope<ContextT>

All Implemented Interfaces:

Scope

Direct Known Subclasses:

InducedContextScope
```
public class ContextScope<ContextT extends TrackableContext<? super ContextT>>
extends Object
implements Scope
```
Scopes objects to the ContextT instance that is current at a given moment (obtained from the associated ContextTracker by default). A ContextScope instance is associated with one particular type of contexts: a subclass of TrackableContext, here denoted as ContextT. For example: a Scope of Contexts of HttpServletRequests.
Instances should usually be created at app startup to be used in bindings in user Modules.
