Description

Interface Summary

CQComparator	This interface extends the java.util.Comparator interface, which defines the compare() method.
ExplicitChangeContext	An entity that implements an explicit change context declares a change context, in which parameters are modified.

Class Summary

ActorTypeUtil	This class includes a number of utility methods and classes that simplify the generation of type constraints.
CalendarQueue	This class implements a fast priority queue.
ConstVariableModelAnalysis	An analysis that traverses a model to determine all the constant variables in a hierarchical model.
DependencyDeclaration	An instance of DependencyDeclaration is an attribute that declares variable dependence information of a parameter.
DFUtilities	This class factors code out of the SDF domain, for use in different schedulers, so that they can be implemented in a consistent fashion.
DFUtilities.NamedObjComparator	A comparator for named objects.
FIFOQueue	A first-in, first-out (FIFO) queue with variable capacity and optional history.
FreeVariableModelAnalysis	An analysis that traverses a model to determine all the free variables in a hierarchical model.
FunctionDependency	This is an abstract base class that describes the dependency that data at an output port has on data at an input port in a firing of the container, which is an entity.
FunctionDependencyOfAtomicActor	An instance of this class describes the dependency that data at an output port has on data at an input port in a firing of the container (an atomic actor).
FunctionDependencyOfCompositeActor	An instance of this class describes the dependency that data at an output port has on data at an input port in a firing of the container (an opaque composite actor).
FuzzyDoubleComparator	Deprecated. As Ptolemy II 4.1, use GeneralComparator instead.
GeneralComparator	This class compares two comparable objects, object_1 and object_2, by calling compare(object_1, object_2).
SuperdenseTime	This class defines the structure of superdense time used in domains having time involved in computation.
Time	An object of the Time class represents model time, as distinct from "wall-clock time," which is time in the physical world.
TimedEvent	This class aggregates an instance of Time and an Object, and provides a CQComparator as an inner class.
TimedEvent.TimeComparator	This class implements the CQComparator interface.
TotallyOrderedSet	An object of this class is a totally ordered set with an increasing order.
