Class com.ibm.agletx.patterns.Meeting
java.lang.Object

+----com.ibm.agletx.patterns.Meeting
- public final class Meeting
- extends Object
- implements Serializable
This Meeting class abstracts light synchronization between
multiple aglets by using a meeting concept. A meeting is established by
creating a meeting object and distribute it among the aglets which
suppose to participate in the meeting.
A meeting object includes:
1. the meeting place (URL)
2. a meeting identifier
3. an optional list of agletIDs, named colleagues, of aglets
which are expected to be presented at the meeting place
4. an optional object (named attachedInfo) describing
additional information regarding the meeting (e.g. list or number of
participants, minimum number of required participants).
Upon arrival to the meeting, an aglet notifies its arrival via
the ready method. As a result all aglets already presented
are notified of its arrival by receiving a special message
(its kind is that of the meeting ID) with the agletID of this newly
arrived aglet.
