Class OcsfmlSystem.clock

class clock : object .. end
Utility class that measures the elapsed time. clock is a lightweight class for measuring time.

Its provides the most precise time that the underlying OS can achieve (generally microseconds or nanoseconds). It also ensures monotonicity, which means that the returned time can never go backward, even if the system time is changed.

Usage example:

    let clock;= new clock in
    let time1 = clock#get_elapsed_time in
    let time2 = clock#restart in
The time value returned by the clock can then be converted to a number of seconds, milliseconds or even microseconds.

method destroy : unit
method get_elapsed_time : Time.t
Get the elapsed time. This function returns the time elapsed since the last call to restart (or the construction of the instance if restart has not been called).
method restart : Time.t
Restart the clock. This function puts the time counter back to zero. It also returns the time elapsed since the clock was started.
