All Implemented Interfaces:

com.google.inject.Scope

public class MapBasedScope
extends Object
implements com.google.inject.Scope

A map-supplier based scope implementation. The scope stores objects in a map which is supplied by a Provider which is specified at creation time of the scope. Each time a scoped object is requested, the provider is queried to access the current scope map. By returning different map instances, different scopes can be distinguished.
