Prefix subprojects with 'smack-'
instead of using the old baseName=smack appendix=project.name approach, we are now going convention over configuration and renaming the subprojects directories to the proper name. Having a prefix is actually very helpful, because the resulting libraries will be named like the subproject. And a core-4.0.0-rc1.jar is not as explicit about what it actually *is* as a smack-core-4.0.0-rc1.jar. SMACK-265

/**
|
||||
* A last activity manager for handling information about the last activity
|
||||
* associated with a Jabber ID. A manager handles incoming LastActivity requests
|
||||
* of existing Connections. It also allows to request last activity information
|
||||
* of other users.
|
||||
* <p>
|
||||
*
|
||||
* LastActivity (XEP-0012) based on the sending JID's type allows for retrieval
|
||||
* of:
|
||||
* <ol>
|
||||
* <li>How long a particular user has been idle
|
||||
* <li>How long a particular user has been logged-out and the message the
|
||||
* specified when doing so.
|
||||
* <li>How long a host has been up.
|
||||
* </ol>
|
||||
* <p/>
|
||||
*
|
||||
* For example to get the idle time of a user logged in a resource, simple send
|
||||
* the LastActivity packet to them, as in the following code:
|
||||
* <p>
|
||||
*
|
||||
* <pre>
|
||||
* XMPPConnection con = new XMPPTCPConnection("jabber.org");
|
||||
* con.login("john", "doe");
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "xray@jabber.org/Smack");
|
||||
* </pre>
|
||||
*
|
||||
* To get the lapsed time since the last user logout is the same as above but
|
||||
* with out the resource:
|
||||
*
|
||||
* <pre>
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "xray@jabber.org");
|
||||
* </pre>
|
||||
*
|
||||
* To get the uptime of a host, you simple send the LastActivity packet to it,
|
||||
* as in the following code example:
|
||||
* <p>
|
||||
*
|
||||
* <pre>
|
||||
* LastActivity activity = LastActivity.getLastActivity(con, "jabber.org");
|
||||
