LnSensorManager

public class LnSensorManager
extends AbstractSensorManager
implements LocoNetListener

Manage the LocoNet-specific Sensor implementation. System names are "LSnnn", where L is the user configurable system prefix, nnn is the sensor number without padding. Valid sensor numbers are in the range 1 to 2048, inclusive. Provides a mechanism to perform the LocoNet "Interrogate" process in order to get initial values from those LocoNet devices which support the process and provide LocoNet Sensor (and/or LocoNet Turnout) functionality.

int iName

Constructor Details

LnSensorManager

public LnSensorManager(LocoNetSystemConnectionMemo memo,
 boolean interrogateAtStart)

Method Details

getMemo

@Nonnull
public LocoNetSystemConnectionMemo getMemo()

Get the system connection for this manager.

Specified by:

getMemo in interface Manager<Sensor>

Overrides:

getMemo in class AbstractManager<Sensor>

Returns:

the system connection for this manager

dispose

public void dispose()

Free resources when no longer used. Specifically, remove all references to and from this object, so it can be garbage-collected.

Specified by:

dispose in interface Manager<Sensor>

Specified by:

dispose in interface SensorManager

Overrides:

dispose in class AbstractManager<Sensor>

createNewSensor

@Nonnull
protected Sensor createNewSensor(@Nonnull
 String systemName,
 String userName)
                          throws IllegalArgumentException

Internal method to invoke the factory and create a new Sensor. Called after all the logic for returning an existing Sensor has been invoked. An existing SystemName is not found, existing UserName not found. Implementing classes should base Sensor on the system name, then add user name.

Specified by:

createNewSensor in class AbstractSensorManager

Parameters:

systemName - the system name to use for the new Sensor

userName - the optional user name to use for the new Sensor

Returns:

the new Sensor

Throws:

IllegalArgumentException - if unsuccessful with reason for fail.

message

public void message(LocoNetMessage l)

Listen for sensor messages, creating them as needed.

Specified by:

message in interface LocoNetListener

Parameters:

l - LocoNet message to be examined

updateAll

public void updateAll()

Requests status updates from all layout sensors.

Specified by:

updateAll in interface SensorManager

Overrides:

updateAll in class AbstractSensorManager

setUpdateBusy

public void setUpdateBusy()

Set Route busy when commands are being issued to Route turnouts.

setUpdateNotBusy

public void setUpdateNotBusy()

Set Route not busy when all commands have been issued to Route turnouts.

allowMultipleAdditions

public boolean allowMultipleAdditions(@Nonnull
 String systemName)

Determines if it is possible to add a range of NamedBeans in numerical order for a particular system implementation.

Default is not providing this service. Systems should override this method if they do provide the service.

Specified by:

allowMultipleAdditions in interface NameIncrementingManager

Parameters:

systemName - the system name to check against; appears to be ignored in all implementations

Returns:

true if possible; false otherwise

createSystemName

@Nonnull
public String createSystemName(@Nonnull
 String curAddress,
 @Nonnull
 String prefix)
                        throws JmriException

Default Sensor ensures a numeric only system name. Create a System Name from hardware address and system letter prefix. AbstractManager performs no validation.

Specified by:

createSystemName in interface SensorManager

Overrides:

createSystemName in class AbstractSensorManager

Parameters:

curAddress - hardware address, no system prefix or type letter.

prefix - - just system prefix, not including Type Letter.

Returns:

full system name with system prefix, type letter and hardware address.

Throws:

JmriException - if unable to create a system name.

validSystemNameFormat

public Manager.NameValidity validSystemNameFormat(@Nonnull
 String systemName)

Test if parameter is a properly formatted system name. Implementations of this method must not throw an exception, log an error, or otherwise disrupt the user.

Specified by:

validSystemNameFormat in interface Manager<Sensor>

Overrides:

validSystemNameFormat in class AbstractManager<Sensor>

Parameters:

systemName - the system name

Returns:

Manager.NameValidity.INVALID if system name does not start with Manager.getSystemNamePrefix(); Manager.NameValidity.VALID_AS_PREFIX_ONLY if system name equals Manager.getSystemNamePrefix(); otherwise Manager.NameValidity.VALID to allow Managers that do not perform more specific validation to be considered valid.

validateSystemNameFormat

@Nonnull
public String validateSystemNameFormat(@Nonnull
 String systemName,
 @Nonnull
 Locale locale)

Validate the format of name, returning it unchanged if valid.

Although further restrictions may be added by system-specific implementations, at a minimum, the implementation must consider a name that does not start with the System Name prefix for this manager to be invalid, and must consider a name that is the same as the System Name prefix to be invalid.

Overriding implementations may rely on Manager.validSystemNameFormat(java.lang.String), however they must provide an actionable message in the thrown exception if that method does not return Manager.NameValidity.VALID. When overriding implementations of this method rely on validSystemNameFormat(), implementations of that method must not throw an exception, log an error, or otherwise disrupt the user.

Specified by:

validateSystemNameFormat in interface Manager<Sensor>

Parameters:

systemName - the system name to validate

locale - the locale for a localized exception; this is needed for the JMRI web server, which supports multiple locales

Returns:

the unchanged value of the name parameter

getBitFromSystemName

public int getBitFromSystemName(String systemName)

Get the bit address from the system name.

Parameters:

systemName - a valid LocoNet-based Turnout System Name

Returns:

the turnout number extracted from the system name

getEntryToolTip

public String getEntryToolTip()

Provide a manager-specific tooltip for the Add new item beantable pane.

Specified by:

getEntryToolTip in interface Manager<Sensor>

Specified by:

getEntryToolTip in interface SensorManager

Overrides:

getEntryToolTip in class AbstractSensorManager

Returns:

the tool tip or null to disable the tool tip

setRestingTime

public void setRestingTime(int rest)

Set "resting time" for the Interrogation process. A minimum of 500 (milliseconds) and a maximum of 200000 (milliseconds) is implemented. Values below this lower limit are forced to the lower limit, and values above this upper limit are forced to the upper limit.

Parameters:

rest - Number of milliseconds (minimum) before sending next LocoNet Interrogate message.

getRestingTime

public int getRestingTime()

get Interrogation process's "resting time"

Returns:

Resting time, in milliseconds
