Its API is similar to that of QTime, - so code that was using that can be ported quickly to the new class. - - However, unlike QTime, QElapsedTimer tries to use monotonic clocks if - possible. This means it's not possible to convert QElapsedTimer objects - to a human-readable time. - - The typical use-case for the class is to determine how much time was - spent in a slow operation. The simplest example of such a case is for - debugging purposes, as in the following example: - - \snippet qelapsedtimer/main.cpp 0 - - In this example, the timer is started by a call to start() and the - elapsed timer is calculated by the elapsed() function. - - The time elapsed can also be used to recalculate the time available for - another operation, after the first one is complete. This is useful when - the execution must complete within a certain time period, but several - steps are needed. The \tt{waitFor}-type functions in QIODevice and its - subclasses are good examples of such need. In that case, the code could - be as follows: - - \snippet qelapsedtimer/main.cpp 1 - - Another use-case is to execute a certain operation for a specific - timeslice. For this, QElapsedTimer provides the hasExpired() convenience - function, which can be used to determine if a certain number of - milliseconds has already elapsed: - - \snippet qelapsedtimer/main.cpp 2 - - \section1 Reference Clocks - - QElapsedTimer will use the platform's monotonic reference clock in all - platforms that support it (see QElapsedTimer::isMonotonic()). This has - the added benefit that QElapsedTimer is immune to time adjustments, such - as the user correcting the time. Also unlike QTime, QElapsedTimer is - immune to changes in the timezone settings, such as daylight-saving - periods. - - On the other hand, this means QElapsedTimer values can only be compared - with other values that use the same reference. This is especially true if - the time since the reference is extracted from the QElapsedTimer object - (QElapsedTimer::msecsSinceReference()) and serialised. These values - should never be exchanged across the network or saved to disk, since - there's no telling whether the computer node receiving the data is the - same as the one originating it or if it has rebooted since. - - It is, however, possible to exchange the value with other processes - running on the same machine, provided that they also use the same - reference clock. QElapsedTimer will always use the same clock, so it's - safe to compare with the value coming from another process in the same - machine. If comparing to values produced by other APIs, you should check - that the clock used is the same as QElapsedTimer (see - QElapsedTimer::clockType()). - - \section2 32-bit overflows - - Some of the clocks used by QElapsedTimer have a limited range and may - overflow after hitting the upper limit (usually 32-bit). QElapsedTimer - deals with this overflow issue and presents a consistent timing. However, - when extracting the time since reference from QElapsedTimer, two - different processes in the same machine may have different understanding - of how much time has actually elapsed. - - The information on which clocks types may overflow and how to remedy that - issue is documented along with the clock types. - - \sa QTime, QTimer -*/ - -/*! - \enum QElapsedTimer::ClockType - - This enum contains the different clock types that QElapsedTimer may use. - - QElapsedTimer will always use the same clock type in a particular - machine, so this value will not change during the lifetime of a program. - It is provided so that QElapsedTimer can be used with other non-Qt - implementations, to guarantee that the same reference clock is being - used. - - \value SystemTime The human-readable system time. This clock is not monotonic. - \value MonotonicClock The system's monotonic clock, usually found in Unix systems. This clock is monotonic and does not overflow. - \value TickCounter The system's tick counter, used on Windows systems. This clock may overflow. - \value MachAbsoluteTime The Mach kernel's absolute time (OS X and iOS). This clock is monotonic and does not overflow. - \value PerformanceCounter The high-resolution performance counter provided by Windows. This clock is monotonic and does not overflow. - - \section2 SystemTime - - The system time clock is purely the real time, expressed in milliseconds - since Jan 1, 1970 at 0:00 UTC. It's equivalent to the value returned by - the C and POSIX \tt{time} function, with the milliseconds added. This - clock type is currently only used on Unix systems that do not support - monotonic clocks (see below). - - This is the only non-monotonic clock that QElapsedTimer may use. - - \section2 MonotonicClock - - This is the system's monotonic clock, expressed in milliseconds since an - arbitrary point in the past. This clock type is used on Unix systems - which support POSIX monotonic clocks (\tt{_POSIX_MONOTONIC_CLOCK}). - - This clock does not overflow. - - \section2 TickCounter - - The tick counter clock type is based on the system's or the processor's - tick counter, multiplied by the duration of a tick. This clock type is - used on Windows platforms. If the high-precision performance - counter is available on Windows, the \tt{PerformanceCounter} clock type - is used instead. - - The TickCounter clock type is the only clock type that may overflow. - Windows Vista and Windows Server 2008 support the extended 64-bit tick - counter, which allows avoiding the overflow. - - On Windows systems, the clock overflows after 2^32 milliseconds, which - corresponds to roughly 49.7 days. This means two processes' reckoning of - the time since the reference may be different by multiples of 2^32 - milliseconds. When comparing such values, it's recommended that the high - 32 bits of the millisecond count be masked off. - - \section2 MachAbsoluteTime - - This clock type is based on the absolute time presented by Mach kernels, - such as that found on OS X. This clock type is presented separately - from MonotonicClock since OS X and iOS are also Unix systems and may support - a POSIX monotonic clock with values differing from the Mach absolute - time. - - This clock is monotonic and does not overflow. - - \section2 PerformanceCounter - - This clock uses the Windows functions \tt{QueryPerformanceCounter} and - \tt{QueryPerformanceFrequency} to access the system's high-precision - performance counter. Since this counter may not be available on all - systems, QElapsedTimer will fall back to the \tt{TickCounter} clock - automatically, if this clock cannot be used. - - This clock is monotonic and does not overflow. - - \sa clockType(), isMonotonic() -*/ - -/*! - \fn QElapsedTimer::QElapsedTimer() - \since 5.4 - - Constructs an invalid QElapsedTimer.
