public class Dcc4PcSensorManager
extends AbstractSensorManager

Constructor Details

Dcc4PcSensorManager

public Dcc4PcSensorManager(Dcc4PcTrafficController tc,
 Dcc4PcSystemConnectionMemo memo)

Method Details

getSensor

public Dcc4PcSensor getSensor(@Nonnull
 String name)

Description copied from class: AbstractSensorManager

Get an existing Sensor or return null if it doesn't exist. Locates via user name, then system name if needed.

Specified by:

getSensor in interface SensorManager

Overrides:

getSensor in class AbstractSensorManager

Parameters:

name - User name or system name to match

Returns:

null if no match found

getMemo

@Nonnull
public Dcc4PcSystemConnectionMemo 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

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.

extractBoardID

void extractBoardID(String systemName)

This extracts the board id out from the system name.

Parameters:

systemName - including system prefix and type letter.

allowMultipleAdditions

public boolean allowMultipleAdditions(@Nonnull
 String systemName)

Description copied from interface: NameIncrementingManager

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

Description copied from class: AbstractSensorManager

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.

notifyReply

public void notifyReply(Dcc4PcReply m)

notifyMessage

public void notifyMessage(Dcc4PcMessage m)

stopPolling

protected void stopPolling()

startPolling

protected final void startPolling()

addBoard

Specified by:

reply in interface Dcc4PcListener

getInputState

void getInputState(int[] longArray,
 int board)

getInputState

int getInputState(int value,
 int input)

decodeInputState

public static String decodeInputState(int state)

decodeDuplicatePacket

int decodeDuplicatePacket(int value,
 int seq,
 Dcc4PcReporter rc)

Determine if the Railcom data is duplicated. If it is then this instructs the Reporter to move things about.

Parameters:

value - Railcom data

seq - message sequence number

rc - Reporter to request action(s) from

Returns:

value calculated locally

pollManager

void pollManager()

createSensorsFromReply

protected void createSensorsFromReply(Dcc4PcReply r)

Generate all the sensor and reporter details based upon the reply message from the board.

Parameters:

r - Reply that we build the information from

validateSystemNameFormat

@Nonnull
public String validateSystemNameFormat(@Nonnull
 String name,
 @Nonnull
 Locale locale)
                                throws NamedBean.BadSystemNameException

Validates to contain at least 1 number . . .

TODO: Custom validation for Dcc4PcSensorManager could be improved. 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:

name - 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

Throws:

NamedBean.BadSystemNameException - if provided name is an invalid format

dispose

public void dispose()

Description copied from class: AbstractManager

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>
