Introduction kernel.util This subpackage of the kernel package provides a collection of utility classes that do not depend on the kernel package. It is separated into a subpackage so that these utility classes can be used without the kernel. The utilities include a collection of exceptions, classes supporting named objects with attributes, lists of named objects, a specialized cross-reference list class, and a thread class that helps Ptolemy keep track of executing threads. math This package encapsulates mathematical functions and methods for operating on matrices and vectors. It also includes a complex number class, a class supporting fractions, and a set of classes supporting fixed-point numbers. matlab This package contains the MATLAB interface. util This package contains various Ptolemy-independent utilities, such as string utilities and XML utilities. actor AbstractReceiver Actor AtomicActor CompositeActor Director Executable ExecutionListener FiringEvent FunctionDependency ... ... actor.util CQComparator CalendarQueue FIFOQueue TimedEvent actor.process FunctionDependencyOfAtomicActor BoundaryDetector FunctionDependencyOfCompositeActor Branch GraphReader BranchController HasFunctionDependencies CompositeProcessDirector InvariantViolationException MailboxBoundaryReceiver IOPort NotifyThread IORelation ProcessDirector Mailbox ProcessReceiver Manager ProcessThread NoRoomException TerminateProcessException NoTokenException QueueReceiver actor.sched Receiver Firing StreamExecutionListener NotSchedulableException TypeAttribute Schedule TypeConflictException ScheduleElement TypedActor Scheduler TypedAtomicActor TypedCompositeActor StaticSchedulingDirector TypedIOPort TypedIORelation actor.parameters TypeEvent TypeListener IntRangeParameter LocationParameter ParameterPort actor.lib actor.gui PortParameter FIGURE 1.14.

Introduction 1.5.2 Overview of Key Classes Some of the key classes in Ptolemy II are shown in figure 1.16. This is a UML static structure diagram (see appendix A of this chapter). The key syntactic elements are boxes, which represent classes, the hollow arrow, which indicates generalization (or subclassing), and other lines, which indicate associations. Some lines have a small diamond, which indicates aggregation. The details of these classes will be discussed in subsequent chapters. Instances of all of the classes shown can have names; they all implement the Nameable interface. Most of the classes generalize NamedObj, which in addition to being nameable can have a list of attributes associated with it. Attributes themselves are instances of NamedObj. Entity, Port, and Relation are three key classes that extend NamedObj, directly or indirectly. These classes define the primitives of the abstract syntax supported by Ptolemy II. They are fully explained in the kernel chapter of volume 2. ComponentPort, ComponentRelation, and ComponentEntity extend these classes by adding support for clustered graphs. CompositeEntity extends ComponentEntity and represents an aggregation of instances of ComponentEntity and ComponentRelation. The actor-oriented class mechanism is represented by the Derivable and Instantiable interfaces. Nearly all classes implement Derivable, which means that they can be contained in class definitions kernel kernel.util graph CPO DirectedAcyclicGraph DirectedGraph Edge Element ElementList Graph GraphActionException GraphConstructionException GraphElementException GraphException GraphStateException GraphTopologyException GraphWeightException Inequality InequalitySolver InequalityTerm LabeledList Node graph.analysis AllPairShortestPathAnalysis Analysis AnalysisException ClusterNodeAnalysis CycleExistenceAnalysis CycleMeanAnalysis InvalidAnalyzerException MaximumProfitToCostRatioAnalysis MirrorTransformation NegativeLengthCycleAnalysis SelfLoopAnalysis SinkNodeAnalysis SourceNodeAnalysis TransitiveClosureAnalysis ZeroLengthCycleAnalysis FIGURE 1.15. The graph package and related packages shown here provide graph-theoretic algorithms that operate on the Ptolemy II data model (figure 1.12) to support of static analysis and scheduling.
