Class AVAnonymousUtils

java.lang.Object

com.avos.avoscloud.AVAnonymousUtils

public class AVAnonymousUtils
extends Object

Provides utility functions for working with Anonymously logged-in users. Anonymous users have some unique characteristics:

• Anonymous users don't need a user name or password.
• Once logged out, an anonymous user cannot be recovered.
• When the current user is anonymous, the following methods can be used to switch to a different user or convert the anonymous user into a regular one:
  • signUp converts an anonymous user to a standard user with the given username and password. Data associated with the anonymous user is retained.
  • logIn switches users without converting the anonymous user. Data associated with the anonymous user will be lost.
  • Service logIn (e.g. Facebook, Twitter) will attempt to convert the anonymous user into a standard user by linking it to the service. If a user already exists that is linked to the service, it will instead switch to the existing user.
  • Service linking (e.g. Facebook, Twitter) will convert the anonymous user into a standard user by linking it to the service.
