public class RealTimePlotter
extends Plotter

This plotter plots input data as a function of elapsed real time in seconds. Elapsed time is set to zero when the initialize() method is invoked. The resolution of time depends on the implementation of the Java virtual machine, but with Sun's JDK 1.3 under Windows 2000, it is 10 milliseconds.

This plotter contains an instance of the Plot class from the Ptolemy plot package as a public member.

Field Detail

input

public TypedIOPort input

Input port, which has type DoubleToken.

Constructor Detail

RealTimePlotter

public RealTimePlotter(CompositeEntity container,
                       java.lang.String name)
                throws IllegalActionException,
                       NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

initialize

public void initialize()
                throws IllegalActionException

Record the start time.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class Plotter

Throws:

IllegalActionException - If the base class throws it.

postfire

public boolean postfire()
                 throws IllegalActionException

Read at most one input from each channel and plot it as a function of time. This is done in postfire to ensure that data has settled.

Specified by:

postfire in interface Executable

Overrides:

postfire in class AtomicActor<TypedIOPort>

Returns:

True if it is OK to continue.

Throws:

IllegalActionException - If there is no director, or if the base class throws it.
