It can often be useful to determine if you are running in a Scope.

You can detect if your code is running within a Scope by calling:


// or


You can also detect if a specific ScopeKey exists by calling:

if (hasScopeKey(ageKey))
   // change my behaviour

/// or

if (Scope.hasScopeKey(ageKey))
   // change my behaviour

Both forms of isWithinScope and hasScopeKey are identical and are provided for consistency with the two forms of the use method.

Detecting if you are within a Scope is really useful for unit testing.

Your unit tests can inject a ScopeKey and change your code can then change its behaviour when running within a unit test.

This can be easier then setting up a full mock framework.
