Class WatchdogTimerConfig

java.lang.Object

jdk.dio.watchdog.WatchdogTimerConfig

All Implemented Interfaces:

DeviceConfig<WatchdogTimer>, DeviceConfig.HardwareAddressing

public class WatchdogTimerConfig
extends java.lang.Object
implements DeviceConfig<WatchdogTimer>, DeviceConfig.HardwareAddressing

The WatchdogTimerConfig class encapsulates the hardware addressing information, and static and dynamic configuration parameters of a watchdog timer.

Some hardware addressing parameter, and static and dynamic configuration parameters may be set to DeviceConfig.DEFAULT. Whether such default settings are supported is platform- as well as device driver-dependent.

An instance of WatchdogTimerConfig can be passed to the DeviceManager.open(DeviceConfig) or DeviceManager.open(Class, DeviceConfig) method to open the designated watchdog timer with the specified configuration. A InvalidDeviceConfigException is thrown when attempting to open a device with an invalid or unsupported configuration.

Constructor Detail

WatchdogTimerConfig

public WatchdogTimerConfig(java.lang.String controllerName,
                   int timerNumber)

Creates a new WatchdogTimerConfig with the specified hardware addressing information.

Parameters:

controllerName - the controller name (such as its device file name on UNIX systems).

timerNumber - the hardware timer's number (a positive or zero integer) or DeviceConfig.DEFAULT.

Throws:

java.lang.IllegalArgumentException - if timerNumber is not in the defined range.

java.lang.NullPointerException - if controller name is null.

WatchdogTimerConfig

public WatchdogTimerConfig(int controllerNumber,
                   int timerNumber)

Creates a new WatchdogTimerConfig with the specified hardware addressing information.

Parameters:

controllerNumber - the controller number (a positive or zero integer) or DeviceConfig.DEFAULT.

timerNumber - the hardware timer's number (a positive or zero integer) or DeviceConfig.DEFAULT.

Throws:

java.lang.IllegalArgumentException - if timerNumber is not in the defined range.

java.lang.NullPointerException - if controller name is null.

Method Detail

getTimerNumber

public int getTimerNumber()

Gets the configured timer number.

Returns:

the timer number (a positive or zero integer); or DeviceConfig.DEFAULT.

getControllerNumber

public int getControllerNumber()

Gets the configured controller number.

Specified by:

getControllerNumber in interface DeviceConfig.HardwareAddressing

Returns:

the controller number (a positive or zero integer) or DeviceConfig.DEFAULT.

getControllerName

public java.lang.String getControllerName()

Gets the configured controller name (such as its device file name on UNIX systems).

Specified by:

getControllerName in interface DeviceConfig.HardwareAddressing

Returns:

the controller name or null.

hashCode

public int hashCode()

Returns the hash code value for this object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

equals

public boolean equals(java.lang.Object obj)

Checks two WatchdogTimerConfig objects for equality.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to test for equality with this object.

Returns:

true if obj is a WatchdogTimerConfig and has the same hardware addressing information and configuration parameter values as this WatchdogTimerConfig object.
