Detailed Description

Base class of all the timer used in this protocol. This is a derived class of TimerHandler.

Constructor & Destructor Documentation

UWAlohaTimer()

UWAloha::UWAlohaTimer::UWAlohaTimer ( UWAloha *  m )

inline

Constructor of UWAlohaTimer Class.

~UWAlohaTimer()

virtual UWAloha::UWAlohaTimer::~UWAlohaTimer ( )

inlinevirtual

Destructor of UWAlohaTimer Class.

Member Function Documentation

freeze()

virtual void UWAloha::UWAlohaTimer::freeze ( )

inlinevirtual

It freezes or in another word, it stops the timer for some time. Suppose, for some reason we want to stop a timer for some period and we want to run this timer from where it was stopped. This function stops the timer and save the left time duration it must run.

References left_duration, start_time, timer_status, UWAloha::UWALOHA_FROZEN, and UWAloha::UWALOHA_RUNNING.

Referenced by UWAloha::stateRxBackoff().

getCounter()

int UWAloha::UWAlohaTimer::getCounter ( )

inline

It provides, how many times a timer ran.

Returns

number of times a timer ran (int).

References counter.

Referenced by UWAloha::getBackoffTime().

getDuration()

double UWAloha::UWAlohaTimer::getDuration ( )

inline

This methods provide the duration of a timer.

Returns

left time duration of a timer (double).

References left_duration.

Referenced by UWAloha::stateBackoff().

incrCounter()

void UWAloha::UWAlohaTimer::incrCounter ( )

inline

Increment the timer counter. It helps to know the statics of the timer.

References counter.

Referenced by UWAloha::getBackoffTime(), and UWAloha::stateTxData().

isActive()

bool UWAloha::UWAlohaTimer::isActive ( )

inline

It tells whether the timer is active or not.

Returns

1 if the timer is active and 0 if it is not.

References timer_status, UWAloha::UWALOHA_FROZEN, and UWAloha::UWALOHA_RUNNING.

Referenced by UWAloha::stateCheckBackoffExpired().

isExpired()

bool UWAloha::UWAlohaTimer::isExpired ( )

inline

Tells whether the timer is expired or not.

Returns

1 if the timer expired and 0 if it is not.

References timer_status, and UWAloha::UWALOHA_EXPIRED.

Referenced by UWAloha::stateCheckBackoffExpired().

isFrozen()

bool UWAloha::UWAlohaTimer::isFrozen ( )

inline

It tells whether the timer is in freeze mode or not.

Returns

1 if the timer is in freeze mode and 0 if it is not.

References timer_status, and UWAloha::UWALOHA_FROZEN.

Referenced by UWAloha::stateBackoff().

isIdle()

bool UWAloha::UWAlohaTimer::isIdle ( )

inline

It tells whether the timer is in Idle state or not.

Returns

1 if the timer is idle and 0 if it is not.

References timer_status, and UWAloha::UWALOHA_IDLE.

isRunning()

bool UWAloha::UWAlohaTimer::isRunning ( )

inline

This method tells whether the timer is in Running state or not.

Returns

1 if the timer is running and 0 if it is not.

References timer_status, and UWAloha::UWALOHA_RUNNING.

resetCounter()

void UWAloha::UWAlohaTimer::resetCounter ( )

inline

Reset the timer counter.

Referenced by UWAloha::stateTxData().

schedule()

virtual void UWAloha::UWAlohaTimer::schedule ( double  val )

inlinevirtual

Schedule the time, i.e., how long a timer is going to run.

Parameters

double

time

References left_duration, start_time, timer_status, and UWAloha::UWALOHA_RUNNING.

Referenced by UWAloha::stateBackoff().

stop()

virtual void UWAloha::UWAlohaTimer::stop ( )

inlinevirtual

Stop the timer any way.

References timer_status, and UWAloha::UWALOHA_IDLE.

Referenced by UWAloha::exitBackoff(), UWAloha::stateIdle(), and UWAloha::stateRxData().

unFreeze()

virtual void UWAloha::UWAlohaTimer::unFreeze ( )

inlinevirtual

It starts the timer from where it was stopped. To run any freeze timer, we can use unfreeze method.
