Class MvpDelegate<Delegated>

java.lang.Object

moxy.MvpDelegate<Delegated>

public class MvpDelegate<Delegated>
extends java.lang.Object

Date: 18-Dec-15 Time: 13:51

This class represents a delegate you can use to extend MVP support to any class.

When using an MvpDelegate, the following lifecycle methods should be forwarded to the delegate:

• onCreate(Bundle)
• onAttach(): inside onStart() of Activity or Fragment
• onSaveInstanceState(android.os.Bundle)
• onDetach(): inside onDestroy() for Activity or onDestroyView() for Fragment
• onDestroy()

Every Object can only be linked with one MvpDelegate instance, so the instance returned from MvpDelegate(Object)} should be kept until the Object is destroyed.
