Class Unmanaged<T>

  • Type Parameters:
    T - type of unmanaged instances
    public class Unmanaged<T>
extends java.lang.Object

    Helper class for injecting and calling lifecycle callbacks unmanaged instances for use by framework and library integrators. 

     Unmanaged<Foo> unmanagedFoo = new Unmanaged<Foo>(Foo.class);
 UnmanagedInstance<Foo> fooInstance = unmanagedFoo.newInstance();
 Foo foo = fooInstance.produce().inject().postConstruct().get();
 ... // Use the foo instance
 fooInstance.preDestroy().dispose();

    An instance of this class can be safely held for the lifetime of the application.

    Unmanaged.UnmanagedInstances created by this class are not suitable for sharing between threads.
