Class Summary

Class	Description
AverageOverTime	An actor to compute the average of the input values received so far over model time.
DateToEvent	A timed actor that accepts DateTokens on the input.
DateToModelTime	A timed actor that outputs the local clock value that corresponds to the date.
Derivative	Output the discrete derivative of the input, y[n] = (x[n] - x[n-1])/dt, where dt is the time gap between input events.
DETransformer	This is an abstract base class for DE actors that transform an input stream into an output stream.
EventButton	Deprecated. Use ptolemy.actor.lib.gui.EventButton, it is domain polymorphic.
EventFilter	An actor that filters a stream of Boolean Tokens.
EventToDate	A timed actor that outputs a date token that corresponds to the current model time (maintained by the local clock in the director).
GetCurrentMicrostep	Deprecated. Use actor.lib.GetCurrentMicrostep instead.
Inhibit	Output a received input token, unless the inhibit port receives a token at the same time.
Integrator	Output the discrete integral of the input.
Merge	A timed merge actor for the DE domain.
MostRecent	Output the most recent input token when the trigger port receives a token.
NonInterruptibleTimer	Deprecated. Use ptolemy.actor.lib.ResettableTimer.
PID	Generate PID output for a given input.
Previous	On each iteration, this actor produces the token received on the previous iteration.
QuantizedSampler	Output the input if the signal has changed more than a quantum value since the last input.
Queue	This actor implements a queue.
Register	A register is a stateful actor with a trigger port that accepts read requests.
Server	This actor models a preemptive server with a fixed or variable service time.
SharedQueue	A queue that outputs the next token to an output channel that is ready to receive it.
SuppressSimultaneousEvents	Output the first token received on the input port, and suppress any other inputs received with the same physical time index.
TestActorPortDepth	An actor supporting regression tests for DEDirector.
TimeCompare	A DE actor to compare the time stamps of events at its two input ports, and output the difference.
TimedDelay	Deprecated. Use actor.lib.TimeDelay.
TimeGap	This actor measures the time interval between arrivals of successive input tokens.
Timer	Deprecated. Use VariableDelay instead, which is essentially identical, or ResettableTimer for a more reasonable timer behavior.
VariableDelay	Deprecated. Use ptolemy.actor.lib.TimeDelay.
WaitingTime	This actor measures the time that events at one input have to wait for events at another.
Wire	Deprecated. Use Sampler instead.
