Direct Known Subclasses:

PublisherTest

public class PublisherNonStrictTest
extends Publisher

This actor publishes input tokens on a named channel and compares the inputs against the value specified by the correctValues parameter.

This actor combines the Publisher actor and the NonStrictTest actor. Thus, it has quite a bit of duplicated code from the NonStrictTest actor.

Note that in the superclass (Publisher), the input is a multiport, whereas in this class it is a regular non-multiport. To use a multiport input, use PublisherTest

Field Detail

correctValues

public Parameter correctValues

A matrix specifying what the input should be. This defaults to a one-by-one array containing a boolean true.

tolerance

public Parameter tolerance

A double specifying how close the input has to be to the value given by correctValues. This is a DoubleToken, with default value 10^-9. During training, if a correct value is greater than 10 orders of magnitude than the tolerance, then the tolerance is changed to a value 9 orders of magnitude less than the correct value. This helps avoid comparisons beyond the precision of a Java double.

trainingMode

public SharedParameter trainingMode

If true, then do not check inputs, but rather collect them into the correctValues array. This parameter is a boolean, and it defaults to false. It is a shared parameter, meaning that changing it for any one instance in a model will change it for all instances in the model.

_firedOnce

protected boolean _firedOnce

Set to true if fire() is called once. If fire() is not called at least once, then throw an exception in wrapup().

_initialized

protected boolean _initialized

Set to true when initialized() is called.

_iteration

protected int _iteration

Count of iterations.

_numberOfInputTokensSeen

protected int _numberOfInputTokensSeen

Number of input tokens seen by this actor in the fire method.

_tolerance

protected double _tolerance

A double that is read from the tolerance parameter specifying how close the input has to be to the value given by correctValues. This is a double, with default value 10^-9.

_trainingTokens

protected java.util.List _trainingTokens

List to store tokens for training mode.

Constructor Detail

PublisherNonStrictTest

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

Construct a publisher with the specified container and name.

Parameters:

container - The container actor.

name - The name of the actor.

Throws:

IllegalActionException - If the actor is not of an acceptable class for the container.

NameDuplicationException - If the name coincides with an actor already in the container.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

If the attribute is the channel, increment the workspace version to force cached receiver lists to be updated, and invalidate the schedule and resolved types of the director, if there is one.

Overrides:

attributeChanged in class NamedObj

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container.

fire

public void fire()
          throws IllegalActionException

Read at most one input token from each input channel and send it to the subscribers, if any.

Specified by:

fire in interface Executable

Overrides:

fire in class Publisher

Throws:

IllegalActionException - If there is no director.

initialize

public void initialize()
                throws IllegalActionException

Override the base class to set the iteration counter to zero.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If the base class throws it or if we are running under the test suite and the trainingMode parameter is set to true.

See Also:

MessageHandler.isNonInteractive()

preinitialize

public void preinitialize()
                   throws IllegalActionException

Override the base class to ensure that links to subscribers have been updated.

Specified by:

preinitialize in interface Initializable

Overrides:

preinitialize in class Publisher

Throws:

IllegalActionException - If there is already a publisher publishing on the same channel.

postfire

public boolean postfire()
                 throws IllegalActionException

Read one token from each input channel and compare against the value specified in correctValues. If the token count is larger than the length of correctValues, then return immediately, indicating that the inputs correctly matched the values in correctValues and that the test succeeded.

Specified by:

postfire in interface Executable

Overrides:

postfire in class AtomicActor<TypedIOPort>

Returns:

True if execution can continue into the next iteration.

Throws:

IllegalActionException - If an input does not match the required value or if the width of the input is not 1.

wrapup

public void wrapup()
            throws IllegalActionException

If trainingMode is true, then take the collected training tokens and store them as an array in correctValues.

Specified by:

wrapup in interface Initializable

Overrides:

wrapup in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If initialized() was called and fire() was not called or if the number of inputs tokens seen is not greater than or equal to the number of elements in the correctValues array.
