Examples of jade.core.Agent

jade.core.Agent
The Agent class is the common superclass for user defined software agents. It provides methods to perform basic agent tasks, such as:
- Message passing using ACLMessage objects, both unicast and multicast with optional pattern matching.
- Complete Agent Platform life cycle support, including starting, suspending and killing an agent.
- Scheduling and execution of multiple concurrent activities.
Application programmers must write their own agents as Agent subclasses, adding specific behaviours as needed and exploiting Agent class capabilities. @author Giovanni Rimassa - Universita' di Parma @author Giovanni Caire - TILAB @version $Date: 2011-06-06 09:17:37 +0200(lun, 06 giu 2011) $ $Revision: 6414 $
