main() {
  xmpp.Connection connection = new xmpp.Connection("user@domain", "password", 5222);
  connection.open();
}

Features

1. Logging

Log level

Client can set logging level of the library with command:

Log.logLevel = LogLevel.VERBOSE;

XMPP traffic logging

Xmpp traffic can be enabled or disabled with:

Log.logXmpp = false

2. Message Archive Management

Feature is work in progress, API is subject to change.

Initial implementation of Message Archive Management.

RST is not yet implemented.

Usage:

• Grabbing the module

connection.getMamModule()

• Querying all messages:

mamManager.queryAll();

• Querying messages based on date (All parameters are optional):

mamManager.queryByTime(start: startTime, end: endTime, jid: buddyJid);

• Querying messages based on messageId (All parameters are optional): This method requires urn:xmpp:mam:2#extended to be supported by the serve, soon it will be available to check feature support.

mamManager.queryById(beforeId: beforeId, afterId: afterId, jid: buddyJid});

Checking capabilities of the server:

mamManager.isQueryByDateSupported
mamManager.isQueryByIdSupported
mamManager.isQueryByJidSupported
