Field Details

parser

MqttContentParser<Turnout> parser

Constructor Details

MqttTurnout

MqttTurnout(MqttAdapter ma,
 String systemName,
 String sendTopic,
 String rcvTopic)

Requires, but does not check, that the system name and topic be consistent

Parameters:

ma - Adapter to reference for connection

systemName - System name of turnout

sendTopic - MQTT topic to use when sending (full string, including systemName part)

rcvTopic - MQTT topic to use when receiving (full string, including systemName part)

Method Details

setParser

public void setParser(MqttContentParser<Turnout> parser)

canInvert

public boolean canInvert()

Description copied from class: AbstractTurnout

Determine if the turnouts can be inverted. If true, inverted turnouts are supported.

Specified by:

canInvert in interface Turnout

Overrides:

canInvert in class AbstractTurnout

Returns:

invert supported

forwardCommandChangeToLayout

protected void forwardCommandChangeToLayout(int s)

Handle a request to change state, typically by sending a message to the layout in some child class. Public version (used by TurnoutOperator) sends the current commanded state without changing it. Implementing classes will typically check the value of s and send a system specific sendMessage command. Sends an MQTT payload command

Specified by:

forwardCommandChangeToLayout in class AbstractTurnout

Parameters:

s - new state value

notifyMqttMessage

public void notifyMqttMessage(String receivedTopic,
 String message)

Specified by:

notifyMqttMessage in interface MqttEventListener

turnoutPushbuttonLockout

protected void turnoutPushbuttonLockout(boolean _pushButtonLockout)

Specified by:

turnoutPushbuttonLockout in class AbstractTurnout

dispose

public void dispose()

Description copied from class: AbstractTurnout

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.

Specified by:

dispose in interface NamedBean

Overrides:

dispose in class AbstractTurnout
