Typhoon provides the following scopes:

##TyphoonScopeObjectGraph (default)

This scope is essential (and unique to Typhoon) for mobile and desktop applications. When a component is resolved, any dependencies with the object-graph will be treated as shared instances during resolution. Once resolution is complete they are not retained by the TyphoonComponentFactory. This allows instantiating an entire object graph for a use-case (say for a ViewController), and then discarding it when that use-case has completed.

##TyphoonScopePrototype

Indicates that a new instance should always be created by Typhoon, whenever this component is obtained from an assembly or referenced by another component.

##TyphoonScopeSingleton

Indicates that Typhoon should retain the instance that exists for as long as the TyphoonComponentFactory exists.

##TyphoonScopeWeakSingleton

Indicates that a shared instance should be created as long as necessary. When your application's classes stop referencing this component it will be deallocated until needed again.
