Re: [ecf-dev] Retrieving nickname from ID

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

Hi Tim,

Good idea.  I've added a new interface to the org.eclipse.ecf.presence API:

org.eclipse.ecf.presence.IChatID

public interface IChatID {
   /**
    * Get username for this ID
    * @return String username for ID
    */
   public String getUsername();
}

And I've implemented (for XMPPID, XMPPRoomID, and IRCID) this interface 
as an adapter off of ID...so the following will now work:

IChatID chatID = (IChatID) id.getAdapter(IChatID.class);
if (chatID != null) {
  String username = chatID.getUsername();
  ...use username here
}

This is checked in the source tree now (Sat 2:30pm pacific time).  And 
by the time you get this email the javadocs on the website will likely 
be updated with the IChatID class.

Thanks for suggestion Tim.

Scott
