public class Constant
extends SimpleDataSource

This is a simple ValueObject creating component. Specification: This component is a simple server that sends out a constant ValueObject when started. It has options to add a Color and non-good quality to the generated ValueObject. This manipulator always fires sometime during the initialization of the logic, not necessarily in any order (see StartupTrigger for a constant that is sent at the end of all other initialization).

Method Detail

addConnector

public void addConnector(Connector connector)
                  throws BadParameterException,
                         VIBUpdateFailedException

Adds an input Connector to this component from the primary outport of a data source. If the component is not screen local then the connector will be updated with the current value of the object.

Overrides:

addConnector in class SimpleDataSource

Parameters:

connector - the connector to be added.

Throws:

BadParameterException - if the targetMethodName does not exist in the listener, or is not

VIBUpdateFailedException - if an update of the connector (by a subclass of this object) fails.

See Also:

#removeaddConnector

getConstantValue

public java.lang.String getConstantValue()

Returns:

Returns the constantValue.

getInitialQuality

public int getInitialQuality()

Returns:

Returns the initialQuality.

getType

public int getType()

Returns:

Returns the type.

isFireLate

public boolean isFireLate()

Returns:

Returns the fireLate.

refreshCurrentValue

public void refreshCurrentValue()

Called on the timebase and sends the current value. The use of a constant with a timebase is questionable, but users seem confused by the idea that a constant sends a value _exactly_ once.

Overrides:

refreshCurrentValue in class SimpleDataSource

See Also:

SimpleDataSource.refreshCurrentValue()

sendValue

public void sendValue()

This will start the server, sending the value.

See Also:

com.ergotech.vib.servers.ExpectationServerInterface#initializationComplete()

setColorHi

public void setColorHi(java.awt.Color newColor)

Overridden to send the value when changed.

Overrides:

setColorHi in class DataSource

Parameters:

newColor - The new Color for the Hi range

See Also:

DataSource.setColorHi(java.awt.Color)

setConstantValue

public void setConstantValue(java.lang.String constantValue)

Parameters:

constantValue - The constantValue to set.

setFireLate

public void setFireLate(boolean fireLate)

Parameters:

fireLate - The fireLate to set.

setInitialQuality

public void setInitialQuality(int initialQuality)

Parameters:

initialQuality - The initialQuality to set.

setSimulationFlag

public void setSimulationFlag(boolean simulationFlag)

This is ignored. We don't care about the simululation state, only a transition to "not simulating".

See Also:

SimulationListener#setSimulationFlag(boolean)

setType

public void setType(int type)

Parameters:

type - The type to set.

simulationStateChanged

public void simulationStateChanged(SimulationChangedEvent simulationChangedEvent)
                            throws java.lang.Exception

Called when the simulation state changes. If the simulation is moving from simulated to not simulating we will re-trigger the constants (and startup triggers).

Throws:

java.lang.Exception

start

public void start()
           throws BadParameterException,
                  VIBUpdateFailedException

This will start the server, sending the value.

Overrides:

start in class SimpleDataSource

Throws:

BadParameterException

VIBUpdateFailedException

See Also:

com.ergotech.vib.servers.ExpectationServerInterface#initializationComplete()

updateColor

public ValueObjectInterface updateColor(ValueObjectInterface newValueObject)

The superclass sets the color according to values/levels which is not what we want for this component. This returns the ValueObject with the correct color set (or not) depending on if sendColors is true or not.

Overrides:

updateColor in class DataSource
