Overview

The SFSBuddy class represent a Buddy in the User’s Buddy List.

Each Buddy has several properties:

  • name: the name of the Buddy, corresponds to the User name
  • nickname: an optional nickname (default = null)
  • isOnline: whether the Buddy is online in the Buddy system or not
  • state: a string representing a “state message”, such as: Available, Busy
  • isBlocked: whether the Buddy is blocked in the User Buddy List
  • isTemp: a temporary Buddy is not stored in the Buddy List, it will be removed at the end of the session (see below)
  • variables: the Buddy variables which can be transient or persistent (see below)

Online State
Any user can decide if they want to be online/off-line as Buddy in the Buddy system. By default a User is online every time he joins the Zone, but the User can also turn off this flag at runtime and disappear from other User’s buddy lists. The Online State is persistent and based on a reserved Buddy Variable.

Blocked Buddies
Buddies that are blocked won’t be able to send any messages to the User, also they won’t be able to see if the Buddy is online/off-line.

Buddy State message
The state message represents a typical IM Buddy state such as Available, Busy etc… By default the system already provides 3 default states: Available, Away, Occupied which can be changed or enriched at any time The state message is based on a reserved Buddy Variable.

Temp Buddy
A temporary Buddy is added to the User List when another User adds me to his Buddy List. This way we can see each others and exchange messages. If I don’t add the User as Buddy in my list the User will remain temporary and it won’t be persisted.

Variables
Buddy Variables enable each Buddy to show/send updates for specific informations to each User that has the Buddy in the list. For example one could send real-time updates on his last activity (ala Twitter) or post the title of the song he’s listening right now, scores, rankings and whatnot.
