Detailed Description

Cross-platform high-resolution periodic timer.

The MainTimer class implements a singleton timer that generates periodic high-resolution timer events. It is designed to be thread-safe and allows other components in the application to synchronize with or wait for timer ticks.

This class supports both Windows and POSIX-compliant systems, providing a consistent interface for time-based operations across platforms.

Member Function Documentation

getCycleCount()

uint64_t MainTimer::getCycleCount

(

)

const

Returns the number of completed wait cycles.

A cycle is recorded each time wait() completes successfully.

Returns

Completed cycle count as an unsigned 64-bit integer.

getCycleMissedTickCount()

uint64_t MainTimer::getCycleMissedTickCount

(

)

const

Returns the number of missed timer ticks in the current cycle.

Indicates how many ticks were missed due to delays in processing.

Returns

Number of missed ticks as an unsigned 64-bit integer.

getElapsedTime()

int64_t MainTimer::getElapsedTime

(

)

const

Returns the total elapsed time since the timer started.

Uses a high-resolution clock to calculate the elapsed time in microseconds.

Returns

Elapsed time in microseconds as a signed 64-bit integer.

getInstance()

MainTimer & MainTimer::getInstance ( )

static

Returns the singleton instance of the MainTimer.

Ensures only one instance of MainTimer exists throughout the application's lifetime. Initializes the timer on the first call.

Returns

Reference to the singleton MainTimer instance.

getTickCount()

uint64_t MainTimer::getTickCount

(

)

const

Returns the current tick count.

Tick count increments with each timer tick and reflects the total number of ticks since the timer was started.

Returns

The current tick count as an unsigned 64-bit integer.

notifyAllListeners()

void MainTimer::notifyAllListeners ( )

static

Notifies all listeners (waiting threads) about a timer tick.

Broadcasts a signal using the condition variable to wake any threads waiting for a tick.

wait()

void MainTimer::wait

(

)

Waits for the next timer tick to occur.

Blocks the current thread until a tick is received. Tracks missed ticks and updates internal state accordingly.

Member Data Documentation

cv

std::condition_variable MainTimer::cv {}

static

Static condition variable used to notify waiting threads of timer ticks.

DELAY

unsigned int MainTimer::DELAY {1}

static

Static delay in milliseconds between each timer tick.
