rocks.frieler.android.beans.scopes.activity.ActivityScopedFactoryBeanHandler

All Implemented Interfaces:

ScopedFactoryBeanHandler

public class ActivityScopedFactoryBeanHandler
extends java.lang.Object
implements ScopedFactoryBeanHandler

ScopedFactoryBeanHandler for the "activity"-scope.

It provides a bean-instance per Activity, always scoped to the foregraound-activity. Due to the limitation of the ViewModelProviders this only works for subtypes of FragmentActivity such as the android.support.v7.app.AppCompatActivity.

The ActivityScopedFactoryBeanHandler supports the ActivityAware-interface.
