Detailed Description

An high resolution time counter.

Member Function Documentation

getRelative()

Relative SC::Time::HighResolutionCounter::getRelative

(

)

const

Converts to a Relative struct.

isLaterThanOrEqualTo()

bool SC::Time::HighResolutionCounter::isLaterThanOrEqualTo

(

HighResolutionCounter

other

)

const

Check if this HighResolutionCounter is later or equal to another HighResolutionCounter.

Parameters

other

The HighResolutionCounter to be used in the comparison

Returns

true if this HighResolutionCounter is later or equal to another HighResolutionCounter
Example:

    Time::HighResolutionCounter start;
    start.snap();
    const Time::HighResolutionCounter end = start.offsetBy(123_ms);
    SC_TEST_EXPECT(end.isLaterThanOrEqualTo(start));
    SC_TEST_EXPECT(not start.isLaterThanOrEqualTo(end));

offsetBy()

HighResolutionCounter SC::Time::HighResolutionCounter::offsetBy

(

Milliseconds

ms

)

const

Returns a HighResolutionCounter offset by a given number of Milliseconds.

Parameters

ms	How many Milliseconds the returned HighResolutionCounter must be offset of

Returns

A HighResolutionCounter that is offset by ms
Example:

    Time::HighResolutionCounter start, end;
    start.snap();
    end = start.offsetBy(Time::Milliseconds(321));
 
    Time::Milliseconds elapsed = end.subtractExact(start).toMilliseconds();
    SC_TEST_EXPECT(elapsed == 321_ms);

snap()

HighResolutionCounter & SC::Time::HighResolutionCounter::snap

(

)

Sets HighResolutionCounter to current instant
Example:

    Time::HighResolutionCounter start, end;
    start.snap();
    Thread::Sleep(100);
    end.snap();
    Time::Milliseconds elapsed = end.subtractExact(start).toMilliseconds();
    SC_TEST_EXPECT(elapsed < 300_ms and elapsed > 0_ms);

subtractApproximate()

Relative SC::Time::HighResolutionCounter::subtractApproximate

(

HighResolutionCounter

other

)

const

Subtracts another HighResolutionCounter from this one, returning an approximate Relative.

Parameters

other

The HighResolutionCounter to be subtracted

Returns

A Relative holding the time interval between the two HighResolutionCounter
Example:

    Time::HighResolutionCounter start, end;
    start.snap();
    end = start.offsetBy(Time::Milliseconds(321));
 
    Time::Milliseconds elapsed = end.subtractExact(start).toMilliseconds();
    SC_TEST_EXPECT(elapsed == 321_ms);

subtractExact()

HighResolutionCounter SC::Time::HighResolutionCounter::subtractExact

(

HighResolutionCounter

other

)

const

Subtracts another HighResolutionCounter from this one, returning a precise HighResolutionCounter.

Parameters

other

The HighResolutionCounter to be subtracted

Returns

A HighResolutionCounter holding the time interval between the two HighResolutionCounter

toMilliseconds()

Milliseconds SC::Time::HighResolutionCounter::toMilliseconds

(

)

const

Converts to Milliseconds.

toNanoseconds()

Nanoseconds SC::Time::HighResolutionCounter::toNanoseconds

(

)

const

Converts to Nanoseconds.

toSeconds()

Seconds SC::Time::HighResolutionCounter::toSeconds

(

)

const

Converts to Seconds.
