A representation of a Jabber ID, or JID.

|
Each JID may have three components: a user, a domain, and an optional

resource. For example: user@domain/resource

|
When a resource is not used, the JID is called a bare JID.

The JID is a full JID otherwise.

Attributes:
|

jid -- Alias for 'full'.

full -- The value of the full JID.
|

bare -- The value of the bare JID.
|
|
user -- The username portion of the JID.
|
|
domain -- The domain name portion of the JID.
|
|
server -- Alias for 'domain'.
|
|
resource -- The resource portion of the JID.

Methods:
|

reset -- Use a new JID value.
