Constructor Detail

BiDiBLight

public BiDiBLight(java.lang.String systemName,
                  BiDiBLightManager mgr)

Create a Light object from system name.

Parameters:

systemName - System name of light to be created

mgr - Light Manager, we get the memo object and the type letter (L) from the manager

Method Detail

getAddr

public BiDiBAddress getAddr()

Description copied from interface: BiDiBNamedBeanInterface

Get the BiDiB address instance

Specified by:

getAddr in interface BiDiBNamedBeanInterface

Returns:

BiDiBAddress

finishLoad

public void finishLoad()

Helper function that will be invoked after construction once the type has been set. Used specifically for preventing double initialization when loading turnouts from XML.

Specified by:

finishLoad in interface BiDiBNamedBeanInterface

nodeNew

public void nodeNew()

Description copied from interface: BiDiBNamedBeanInterface

called then a new node has been discovered

Specified by:

nodeNew in interface BiDiBNamedBeanInterface

nodeLost

public void nodeLost()

Description copied from interface: BiDiBNamedBeanInterface

called then a node was lost

Specified by:

nodeLost in interface BiDiBNamedBeanInterface

getMemo

public BiDiBSystemConnectionMemo getMemo()

Get connection memo from a light object

Returns:

BiDiB connection memo instance

getAddress

public BiDiBAddress getAddress()

Get addres object from a light object

Returns:

BiDiB address instance

dispose

public void dispose()

Dispose of the light object. Remove the Message Listener for this light object

Specified by:

dispose in interface NamedBean

Overrides:

dispose in class AbstractNamedBean

isIntensityVariable

public boolean isIntensityVariable()

Check if this object can handle variable intensity.

Returns:

true for some LC output types, false for others

isTransitionAvailable

public boolean isTransitionAvailable()

Can the Light change its intensity setting slowly?

If true, this Light supports a non-zero value of the transitionTime property, which controls how long the Light will take to change from one intensity level to another. BiDiB LIGHTPORTs have internal dimming via port configuration.

Unbound property

Specified by:

isTransitionAvailable in interface VariableLight

Overrides:

isTransitionAvailable in class AbstractVariableLight

Returns:

true if isIntensityVariable() is true but for a LIGHTPORT return false.

setState

public void setState(int newState)

Set the current state of this Light. This routine requests the hardware to change.

Specified by:

setState in interface Light

Specified by:

setState in interface NamedBean

Overrides:

setState in class AbstractVariableLight

Parameters:

newState - new requested state - must be ON or OFF

setTargetIntensity

public void setTargetIntensity(double intensity)

Set the intended new intensity value for the Light. If transitions are in use, they will be applied.

Bound property between 0 and 1.

A value of 0.0 corresponds to full off, and a value of 1.0 corresponds to full on.

Values at or below the minIntensity property will result in the Light going to the OFF state immediately. Values at or above the maxIntensity property will result in the Light going to the ON state immediately.

Specified by:

setTargetIntensity in interface VariableLight

Overrides:

setTargetIntensity in class AbstractVariableLight

Parameters:

intensity - the desired brightness

sendLcOutput

protected void sendLcOutput(int portstat)

Send request to traffic controller

Parameters:

portstat - BiDiB portstat value (see protocol description for valid values)

sendIntensity

protected void sendIntensity(double intensity)

Send a Dim/Bright commands to the hardware to reach a specific intensity.

Specified by:

sendIntensity in class AbstractVariableLight

Parameters:

intensity - new intensity

receiveIntensity

public void receiveIntensity(int portstat)

Transfer incoming change event to JMRI

Parameters:

portstat - BiDiB portstat value (see protocol description for valid values)

sendOnOffCommand

protected void sendOnOffCommand(int newState)

Description copied from class: AbstractVariableLight

Send a On/Off Command to the hardware

Specified by:

sendOnOffCommand in class AbstractVariableLight

Parameters:

newState - new state

getNumberOfSteps

protected int getNumberOfSteps()

Description copied from class: AbstractVariableLight

Provide the number of steps available between min and max intensity

Specified by:

getNumberOfSteps in class AbstractVariableLight

Returns:

number of steps
