Interface Summary

Collector	A Collector can be given new elements and can return the "result" derived from those elements.
Function0	An interface for functions of zero arguments.
Function1	An interface for functions of one argument.
Function2	An interface for functions of two arguments.
Function3	An interface for functions of three arguments.
IPC.CommunicationStrategy	An object that determines how various IPC operations are performed.
IPC.Connection	An object that can send and receive.
IPC.DestinationTable	A mapping from destination names to the data needed to establish connections with the corresponding agents.
IPC.InputMessage	An object that represents an incoming message.
IPC.MessageListener	An object that is notified when a message is received.
IPC.SocketlikeCommunicationStrategy	A CommunicationStrategy that provides "connections" analogous to sockets and a visible mapping from destination names to the data needed to establish a connection.
Markable	An interface for markable objects.
Predicate0	An interface for boolean functions of zero arguments
Predicate1	An interface for boolean functions of one argument.
Predicate2	An interface for boolean functions of two arguments.
TextAreaFrame.TListener

Class Summary

CommandLoop
Debug	Class for useful static debugging tools
DefaultFont
ImageCanvas
IPC	Support for interprocess communication in a framework that allows different communication strategies to be used in a uniform way.
IPC.BasicDestinationTable	A HashMap implementation of the DestinationTable interface.
IPC.BasicInputMessage	A minimal implementation of InputMessage.
IPC.ObjectStreamCommunicationStrategy	A communication strategy in which a destination is mapped to a host and port number, and objects are sent by writing their serialization to a socket.
IPC.ObjectStreamConnection	A Connection that is used to send and receive serialized objects via a socket.
IPC.ObjectStreamNameServer	A Thread that acts as a name-server on a specified port.
IPC.ObjectStreamServer	A Thread that accepts connections to a ServerSocket and creates an object-reading thread for each connection.
IPC.ServiceAddress	An object that contains a host name and a port number.
IPC.SimpleIXCommunicationStrategy	An ObjectStream communication strategy that provides default host and port assignments for standard I-X agents.
IPC.SimpleIXDestinationTable	A DestinationTable that provides default host and port assignments for standard I-X agents, suitable for use with an instance of ObjectStreamCommunicationStrategy.
IPC.SimpleIXXMLCommunicationStrategy	An ObjectStream communication strategy that provides default host and port assignments for standard I-X agents and encodes the message contents in XML rather than serializing.
IPC.XMLObjectStreamCommunicationStrategy	A version of ObjectStreamCommunicationStrategy that encodes the message contents in XML rather than serializing.
Mark	A class used when marking objects as used, visited, etc.
MessageQueue	MessageQueues can be used for messages between threads.
MultiHashtable	A MultiHashtable is (by weak analogy with "multiset") a Hashtable that maps each key to a collection of values.
Parameters	The Parameters class contains methods that allow information from application command-line arguments and from Applet parameters to be used in a uniform way.
Parameters.AccessRecordingProperties
Seq	Seq defines some convenient methods for use with sequences, where a sequence is an Object[], a Vector, a LList, or an Enumeration.
Seq.IteratorEnumeration
TextAreaFrame	A TextArea that has its own frame and some buttons.
TwoKeyHashMap
Util	Class for useful static methods.
Util.NameGenerator	Name generator a la gensym.
ViewColor
WaitImage

Exception Summary

IPC.IPCException
