CooperationDomain	Acts as a meeting room for other agents.
CooperationDomainObserver	`CooperationDomainObserver` is a subclass of `Agent` with the sole purpose of observing all messages sent in a `CooperationDomain`, it only sends messages to its members after having recieved a corresponding message, so observing its recieved messages should be enough to observe its activity.
DataStorageDescriptor	Copyright: Copyright 2003-2014, Knowledge Science Group, University of Calgary.
EventNotificationURL	Title: EventNotificationURL
EventQueue
ExitChecker	Since we can't trust that AWT or some other thread is spinning and keeping the process alive when we exit, we should explicitly kill the process if we can't find any CASA agent threads or a main program (assumed to be a thread named "main").
IPSocket	This class is an extremely thin (and trasparent) holder/wrapper for the java.net.Socket class.
ItemBuffer<T>	This is a thin wrapper for java.util.LinkedList.

SecureProxy	`SecureProxy` is a simple subclass of `AgentProxy` created with the sole purpose of acting as a proxy between the agent that it protects and all other agents.
ServiceDescriptor
Status	An object combining a status integer and an explanation `String`.

Test1
TokenParser
TransientAgent	Base abstract class for all classes to exhibit Agent behavior.
TransientAgent.NewAgentLispCommand	Class to implement the (OPTIONS ...) lisp command.
XMLMessage	Title: CASA Description: Based on the KQMLmessage class.
YellowPagesAgent	`YellowPagesAgent` is an extension of `Agent` that acts as an advertisement service for other agents. Yellow pages accept requests to advertise and to remove an existing advertisement. Yellow pages store their advertisement list between sessions if they are set persistent. Yellow pages accept requests to search for a given advertisement in their advertisement list.

Package casa Description

The casa package is the main package for CASA (Collaborative Agent System Architecture), which is an infrastructure for agent based systems.

See CASA overview documentation.

The important classes if you interested in implementing agents are:

Agent a persistent, full-functioning agent. You should inherit from this class when building most agents.
ML An interface containing constant strings used in MLMesssage.
MLMessage Base class for XMLMessage and KQMLMessage. Contains the most basic, necessary functions for a markup message in the CASA package. Also contains functionality for interfacing with XML and KQML messages. That is, the field markupLanguage determines the type of message (XML/KQML) to be returned by the getNewMLMessage function. This is basically a key/value map where the keys represent the message field names, and the values represent the corresponding values.
URLDescriptor represents URL strings are of the form casa://user@host:port/dir/file#fragment?key=value&key=value. Agent communication and messages use URLs to identify all agents.
PerformDescriptor A simple description consisting of key/value pairs. It is an extension of TreeMap with a Status properties added. PerformDescriptor is usually used to return information from an agent processing a message. The policies call callback methods to allow the agent to process the message appropriately (if at all), and use the information returned in the PerformDescriptor to modify behaviour. For example, if a reply is normally called for, the type of the reply will be modified depending on the Status object in the returned PerformDescriptor, but the key/value pairs always override whatever the "normative" key/value pairs in any reply message.
Status A simple combination of an status int and a text description String used to return status values from many methods. The value part's meaning is taken to be:
- <0: error (an explanation is expected int String description part)
- 0: success
- >0: warning (a qualified success, usually with some explanation)
