Description

Interface Summary
BoundedGraph | A simple "view" interface for directed graphs that have unique start and finish nodes.
Collector | A Collector can be given new elements and can return the "result" derived from those elements.
DirectedGraph | A simple "view" interface for directed graphs.
Fn1<K,V> | An interface for functions of one argument.
Function0 | An interface for functions of zero arguments.
Function1 | An interface for functions of one argument.

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.

MultiMap |
PatternParser.Parser |

TextAreaFrame.TListener |
TransitiveClosure | The transitive closure of a relation that can be treated as directed graph.
TypedList<E> | A List whose elements must be instances of a particluar subclass of Object.
UndoAction | An object used to undo something.

Class Summary
AbstractDirectedGraph | A utility class that makes it easier to define a DirectedGraph.
AbstractUndoAction | Base implementation of an object used to undo something.
AgentLauncher |
CatchingThread | A thread that catches and reports errors or exceptions.
Collect | Collection and Map utilities
Collect.ShortestFirstComparator | A Comparator that orders shorter Collections before longer ones.
ColorGenerator | A source of "nice" colors for use in GUIs.
DAGTransitiveClosure | The transitive closure of a directed acyclic graph (DAG).
Debug | Class for useful static debugging tools
DeepCopier | Copies Objects, recursively copying subobjects.
Duration | The difference between two dates.
EnumeratedValue | Base/utility class for type-safe enumerated values.
FanComposer | Composes Object-to-Collection mappings ("fans").
FileExtensionFileFilter |
Fn | Function utilities
FullTransitiveClosure | The transitive closure of a relation (cycles are allowed).
FutureValue | Computes a value in a separate thread.
Gensym | Name and ID generator a la gensym.
Gensym.Generator | A name and ID generator.
Graphs | Static graph utilities.
Inf | Very simple arithmetic with a pretend positive infinity.
IntRef | A modifiable reference to an int.
IO | Class for useful static I/O methods that don't belong anywhere else.
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.BufferedMessageListener | A MessageListener that enqueues messages for processing in a separate thread of the listener's own.
IPC.EmptyCommunicationStrategy | A strategy that just throws an exception whenever the agent tries to send.
IPC.SimpleIXCommunicationStrategy | An ObjectStream communication strategy for I-X agents.
IPC.SimpleIXXMLCommunicationStrategy | An XMLObjectStream communication strategy for I-X agents.
IPC.XMLObjectStreamCommunicationStrategy | A version of ObjectStreamCommunicationStrategy that encodes the message contents in XML rather than serializing.
ISODateFormat | Converts between Dates and ISO 8601 strings.
JavaNameWordIterator | An iterator that returns successive words from a name that follows Java capitalization conventions.
LCNameMapper | Maps both ways between short names, in lower-case, and long names.
ListOf | Static util methods for `TypedList`s.
Mark | A class used when marking objects as used, visited, etc.
MessageQueue | A queue for messages between threads.
MultiHashMap | A MultiHashMap is (by weak analogy with "multiset") a HashMap that maps each key to a collection of values.
Name | Wrapper for relatively short strings used as names.
NameMapper | Maps both ways between short and long names.
ObjectComparator | Provides a total ordering for arbitrary objects.
ObjectCopier | Copies Objects.
ObjectWalker | Walks objects.
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.
PatternParser | A simple framework for conversion in both directions between `LList` and String representations of pattern "sentences".
PatternParser.LispPatternParser | A parser that uses a Lisp-like syntax.
Patterns | A class for pattern-related utilities.
Proc | Procedure objects.
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 |
SimpleStringBuffer | Simple version of StringBuffer without synchronized methods and with no ability to grow beyond its initial capacity.
StableHashMap |
Strings | A class containing useful static string methods.
StructuralEquality | Compares two objects to see whether they have the same values in the same places.
TextAreaFrame | A text area that has its own frame and some buttons.
ThreadCondition | Handles waiting for a condition to be made true by another thread.
TopologicalSorter | DAG topological sort, returning ancestors before descendents.
TransferThread | A thread that processes a message queue.
TwoKeyHashMap |
UniqueObject | Objects used just to be distinct from other objects.
Util | Class for useful static methods that don't belong anywhere else.
WithCleanup | A class that encapsulates the tricks needed to use a "finally" clause that might throw an exception.

Exception Summary
