Constructor Detail

AbstractSensorManager

public AbstractSensorManager()

Method Detail

getXMLOrder

public int getXMLOrder()

Specified by:

getXMLOrder in interface Manager

Specified by:

getXMLOrder in class AbstractManager

typeLetter

public char typeLetter()

Specified by:

typeLetter in interface Manager

Returns:

The type letter for a specific implementation

provideSensor

public Sensor provideSensor(String name)

Description copied from interface: SensorManager

Locate via user name, then system name if needed. If that fails, create a new sensor: If the name is a valid system name, it will be used for the new sensor. Otherwise, the makeSystemName method will attempt to turn it into a valid system name.

Specified by:

provideSensor in interface SensorManager

Parameters:

name - User name, system name, or address which can be promoted to system name

Returns:

Never null

getSensor

public Sensor getSensor(String name)

Description copied from interface: SensorManager

Locate via user name, then system name if needed. Does not create a new one if nothing found

Specified by:

getSensor in interface SensorManager

Returns:

null if no match found

isNumber

boolean isNumber(String s)

getBySystemName

public Sensor getBySystemName(String key)

Specified by:

getBySystemName in interface SensorManager

getInstanceBySystemName

protected Object getInstanceBySystemName(String systemName)

Description copied from class: AbstractManager

Locate an instance based on a system name. Returns null if no instance already exists. This is intended to be used by concrete classes to implement their getBySystemName method. We can't call it that here because Java doesn't have polymorphic return types.

Overrides:

getInstanceBySystemName in class AbstractManager

Returns:

requested Turnout object or null if none exists

getByUserName

public Sensor getByUserName(String key)

Specified by:

getByUserName in interface SensorManager

normalizeSystemName

protected String normalizeSystemName(String sysName)

newSensor

public Sensor newSensor(String sysName,
                        String userName)

Description copied from interface: SensorManager

Return an instance with the specified system and user names. Note that two calls with the same arguments will get the same instance; there is only one Sensor object representing a given physical turnout and therefore only one with a specific system or user name.

This will always return a valid object reference; a new object will be created if necessary. In that case:

• If a null reference is given for user name, no user name will be associated with the Sensor object created; a valid system name must be provided
• If both names are provided, the system name defines the hardware access of the desired sensor, and the user address is associated with it. The system name must be valid.

Note that it is possible to make an inconsistent request if both addresses are provided, but the given values are associated with different objects. This is a problem, and we don't have a good solution except to issue warnings. This will mostly happen if you're creating Turnouts when you should be looking them up.

Specified by:

newSensor in interface SensorManager

Returns:

requested Sensor object (never null)

createNewSensor

protected abstract Sensor createNewSensor(String systemName,
                                          String userName)

Internal method to invoke the factory, after all the logic for returning an existing method has been invoked.

Returns:

new null

updateAll

public void updateAll()

Requests status of all layout sensors under this Sensor Manager. This method may be invoked whenever the status of sensors needs to be updated from the layout, for example, when an XML configuration file is read in. Note that this null implementation only needs be implemented in system-specific Sensor Managers where readout of sensor status from the layout is possible.

Specified by:

updateAll in interface SensorManager

allowMultipleAdditions

public boolean allowMultipleAdditions(String systemName)

A method that determines if it is possible to add a range of sensors in numerical order eg 10 to 30, primarily used to enable/disable the add range box in the add sensor panel

Specified by:

allowMultipleAdditions in interface SensorManager

createSystemName

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

Specified by:

createSystemName in interface SensorManager

Throws:

JmriException

getNextValidAddress

public String getNextValidAddress(String curAddress,
                                  String prefix)

Description copied from interface: SensorManager

Determine if the address supplied is valid and free, if not then it shall return the next free valid address up to a maximum of 10 address away from the initial address.

Specified by:

getNextValidAddress in interface SensorManager

Parameters:

curAddress - - The hardware address of the turnout we which to check.

prefix - - The System Prefix used to make up the systemName

public long getDefaultSensorDebounceGoingInActive()

Specified by:

public void setDefaultSensorDebounceGoingActive(long timer)

Specified by:
