public class Plot
extends Event
implements ConfigurableEntity

An event to plot the received arguments as points in a timed plotter. It implicitly contains a TimedPlotter in a Configurer, so that it can reuse the function provided by the timed plotter and the timed plotter can also be configured with the configuration for this event itself. This event can receive 0 to more arguments. Each argument corresponds to a distinct data set displayed in the plotter (usually in a unique color). When this event is fired, for each arguments that can be converted into double tokens, it plots the values of those arguments in the plotter with the current model time on the x-axis.

Field Detail

_configurer

private Configurer _configurer

The configurer to contain the timed plotter.

_plotter

private TimedPlotter _plotter

The timed plotter used to plot the data.

Constructor Detail

Plot

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

Construct an event with the given name contained by the specified composite entity. The container argument must not be null, or a NullPointerException will be thrown. This event will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace. This constructor write-synchronizes on the workspace.

Parameters:

container - The container.

name - The name of the state.

Throws:

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

NameDuplicationException - If the name coincides with that of an entity already in the container.

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the state into the specified workspace. This calls the base class and then sets the attribute and port public members to refer to the attributes and ports of the new state.

Overrides:

clone in class Event

Parameters:

workspace - The workspace for the new event.

Returns:

A new event.

Throws:

java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

configure

public void configure(java.net.URL base,
                      java.lang.String source,
                      java.lang.String text)
               throws java.lang.Exception

Configure the object with data from the specified input source (a URL) and/or textual data. The object should interpret the source first, if it is specified, followed by the literal text, if that is specified. The new configuration should usually override any old configuration wherever possible, in order to ensure that the current state can be successfully retrieved.

This method is defined to throw a very general exception to allow classes that implement the interface to use whatever exceptions are appropriate.

Specified by:

configure in interface Configurable

Overrides:

configure in class State

Parameters:

base - The base relative to which references within the input are found, or null if this is not known, or there is none.

source - The input source, which specifies a URL, or null if none.

text - Configuration information given as text, or null if none.

Throws:

java.lang.Exception - If something goes wrong.

fire

public Event.RefiringData fire(Token arguments)
                        throws IllegalActionException

Process this event with the given arguments. The number of arguments provided must be equal to the number of formal parameters defined for this event, and their types must match. The actions of this event are executed.

Overrides:

fire in class Event

Parameters:

arguments - The arguments used to process this event.

Returns:

A refiring data structure that contains a non-negative double number if refire() should be called after that amount of model time, or null if refire() need not be called.

Throws:

IllegalActionException - If the number of the arguments or their types do not match, the actions cannot be executed, or any expression (such as guards and arguments to the next events) cannot be evaluated.

See Also:

Event.refire(Token, RefiringData)

getConfigureSource

public java.lang.String getConfigureSource()

Return the input source that was specified the last time the configure method was called.

Specified by:

getConfigureSource in interface Configurable

Overrides:

getConfigureSource in class State

Returns:

The string representation of the input URL, or null if the no source has been used to configure this object, or null if no external source need be used to configure this object.

getConfigureText

public java.lang.String getConfigureText()

Return the text string that represents the current configuration of this object. Note that any configuration that was previously specified using the source attribute need not be represented here as well.

Specified by:

getConfigureText in interface Configurable

Overrides:

getConfigureText in class State

Returns:

A configuration string, or null if no configuration has been used to configure this object, or null if no configuration string need be used to configure this object.

getConfigurer

public Configurer getConfigurer()

Get the Configurer object for this entity.

Specified by:

getConfigurer in interface ConfigurableEntity

Overrides:

getConfigurer in class State

Returns:

the Configurer object for this entity.

_exportMoMLContents

protected void _exportMoMLContents(java.io.Writer output,
                                   int depth)
                            throws java.io.IOException

Write a MoML description of the contents of this object, which in this class are the attributes plus the ports. This method is called by exportMoML(). Each description is indented according to the specified depth and terminated with a newline character.

Overrides:

_exportMoMLContents in class State

Parameters:

output - The output to write to.

depth - The depth in the hierarchy, to determine indenting.

Throws:

java.io.IOException - If an I/O error occurs.

See Also:

NamedObj.exportMoML(Writer, int)

_initializePlotter

private void _initializePlotter()
                         throws IllegalActionException

Initialize the timed plotter in the configurer.

Throws:

IllegalActionException - If the plotter cannot be initialized.
