public class BiDiBSignalMast
extends AbstractSignalMast
implements BiDiBNamedBeanInterface

This class implements a SignalMast that use BiDiB Accessories to set aspects.

This implementation writes out to BiDiB when it's commanded to change appearance, and updates its internal state when it receives a status feedback from BiDiB.

System name specifies the creation information:

 BF$bsm:basic:one-searchlight(123)
 

The name is a colon-separated series of terms:

• B - system prefix
• F$bsm - defines signal masts of this type
• basic - name of the signaling system
• one-searchlight - name of the particular aspect map
• (node:123) - BiDiB Accessory address

To keep the state consistent, setAspect(java.lang.String) does not immediately change the local aspect. Instead, it produces the relevant BiDiB message on the network, waiting for that to return and do the local state change, notification, etc.

setAspect

public void setAspect(@Nonnull
                      java.lang.String aspect)

Description copied from interface: SignalMast

Set aspect to a valid name in the current signal system definition.

Specified by:

setAspect in interface SignalMast

Overrides:

setAspect in class AbstractSignalMast

Parameters:

aspect - the new aspect shown

setLit

public void setLit(boolean newLit)

Description copied from class: AbstractSignalMast

Set the lit property.

This acts on all the SignalHeads included in this SignalMast

Specified by:

setLit in interface Signal

Specified by:

setLit in interface SignalMast

Overrides:

setLit in class AbstractSignalMast

Parameters:

newLit - the new value of lit

queryAccessory

public void queryAccessory()

Request the state of the accessory from the layout. The listener gets the answer.

Specified by:

getAddr in interface BiDiBNamedBeanInterface

Returns:

BiDiBAddress

nodeNew

public void nodeNew()

called then a new node has been discovered

Specified by:

nodeNew in interface BiDiBNamedBeanInterface

nodeLost

public void nodeLost()

called then a node was lost

Specified by:

dispose

public void dispose()

Deactivate this object, so that it releases as many resources as possible and no longer effects others.

For example, if this object has listeners, after a call to this method it should no longer notify those listeners. Any native or system-wide resources it maintains should be released, including threads, files, etc.

It is an error to invoke any other methods on this object once dispose() has been called. Note, however, that there is no guarantee about behavior in that case.

Afterwards, references to this object may still exist elsewhere, preventing its garbage collection. But it's formally dead, and shouldn't be keeping any other objects alive. Therefore, this method should null out any references to other objects that this NamedBean contained. Remove the Message Listener for this signal mast

Specified by:

dispose in interface NamedBean

Overrides:

dispose in class AbstractNamedBean

isAccessoryAddressUsed

public static java.lang.String isAccessoryAddressUsed(BiDiBAddress address)
