                        Map<String,Object> properties)

deactivate

protected void deactivate(org.osgi.service.component.ComponentContext componentContext)

updated

public void updated(Map<String,Object> properties)

startWatchdog

public void startWatchdog()

Description copied from interface: WatchdogService

Starts the hardware watchdog on the device. If a timeout value has not been set, the watchdog will use its default timeout.

Specified by:

startWatchdog in interface WatchdogService

stopWatchdog

public void stopWatchdog()

Description copied from interface: WatchdogService

Stops the hardware Watchdog on the device

Specified by:

stopWatchdog in interface WatchdogService

getHardwareTimeout

public int getHardwareTimeout()

Description copied from interface: WatchdogService

Returns the timeout value for the hardware watchdog in increments of milliseconds.

Specified by:

getHardwareTimeout in interface WatchdogService

Returns:

An int representing the hardware timeout value in milliseconds.

registerCriticalService

public void registerCriticalService(CriticalComponent criticalComponent)

Description copied from interface: WatchdogService

Register a critical service with the Critical Service Check-in. Once registered, the critical service must call the checkin() method (at a frequency higher than 1/timeout) to prevent a system reboot.

Specified by:

registerCriticalService in interface WatchdogService

unregisterCriticalService

public void unregisterCriticalService(CriticalComponent criticalComponent)

Description copied from interface: WatchdogService

Unregister a critical service with the Critical Service Check-in. Once unregistered, the critical service will no longer call the checkin() method.

Specified by:

unregisterCriticalService in interface WatchdogService

getCriticalComponents

public List<CriticalComponent> getCriticalComponents()

Description copied from interface: WatchdogService

Returns the list of the currently registered CriticalComponents

Specified by:

getCriticalComponents in interface WatchdogService

Returns:

A List of CriticalComponents

checkin

public void checkin(CriticalComponent criticalService)

Description copied from interface: WatchdogService

This method is used to notify the Watchdog Service that a critical service has 'checked in' and the reboot timer should be reset.

Specified by:

checkin in interface WatchdogService

Parameters:

criticalService - A criticalService to be updated.

isConfigEnabled

public boolean isConfigEnabled()

setConfigEnabled

public void setConfigEnabled(boolean configEnabled)
