Constant Summary collapse
- STREAM_NS =
'http://etherx.jabber.org/streams'
Instance Attribute Summary collapse
-
#jid ⇒ Object
Returns the value of attribute jid.
-
#password ⇒ Object
Returns the value of attribute password.
Class Method Summary collapse
-
.connect(host, port, conn, client, jid, pass) ⇒ Object
Attempt a connection Stream will raise
NoConnection
if it receives #unbind before #post_init this catches that and returns false prompting for another attempt. -
.start(client, jid, pass, host = nil, port = 5222) ⇒ Object
Start the stream between client and server [client] must be an object that will respond to #call and #jid= [jid] must be a valid argument for JID.new (see JID) [pass] must be the password [host] (optional) must be the hostname or IP to connect to.
Instance Method Summary collapse
-
#connection_completed ⇒ Object
Called when EM completes the connection to the server this kicks off the starttls/authorize/bind process.
-
#initialize(client, jid, pass) ⇒ Stream
constructor
Called by EM.connect to initialize stream variables.
- #post_init ⇒ Object
-
#receive(node) ⇒ Object
Called by the parser with parsed nodes.
-
#receive_data(data) ⇒ Object
Called by EM with data from the wire.
-
#send(stanza) ⇒ Object
Send data over the wire The argument for this can be anything that responds to #to_s.
-
#unbind ⇒ Object
Called by EM when the connection is closed.

.start(client, jid, pass, host = nil, port = 5222) ⇒ Object
Start the stream between client and server
[client] must be an object that will respond to #call and #jid=
[jid] must be a valid argument for JID.new (see JID)
[pass] must be the password
[host] (optional) must be the hostname or IP to connect to. defaults to the domain of [jid]
[port] (optional) must be the port to connect to. defaults to 5222
