Method Detail

osvrTimeValueGetNow

public static void osvrTimeValueGetNow(OSVR_TimeValue dest)

Gets the current time in the TimeValue. Parallel to gettimeofday. Original signature : void osvrTimeValueGetNow(OSVR_TimeValue*)

osvrTimeValueToStructTimeval

public static void osvrTimeValueToStructTimeval(OsvrTimeValueLibrary.timeval dest,
                                                OSVR_TimeValue src)

Converts from a TimeValue struct to your system's struct timeval.

Parameters:

dest - Pointer to an empty struct timeval for your platform.

src - A pointer to an OSVR_TimeValue you'd like to convert from.
If either parameter is NULL, the function will return without doing
anything.
Original signature : void osvrTimeValueToStructTimeval(timeval*, const OSVR_TimeValue*)

osvrStructTimevalToTimeValue

public static void osvrStructTimevalToTimeValue(OSVR_TimeValue dest,
                                                OsvrTimeValueLibrary.timeval src)

Converts from a TimeValue struct to your system's struct timeval.

Parameters:

dest - An OSVR_TimeValue destination pointer.

src - Pointer to a struct timeval you'd like to convert from.
The result is normalized.
If either parameter is NULL, the function will return without doing
anything.
Original signature : void osvrStructTimevalToTimeValue(OSVR_TimeValue*, timeval*)

osvrTimeValueNormalize

public static void osvrTimeValueNormalize(OSVR_TimeValue tv)

"Normalizes" a time value so that the absolute number of microseconds is less than 1,000,000, and that the sign of both components is the same.

Parameters:

tv - Address of a struct TimeValue to normalize in place.
If the given pointer is NULL, this function returns without doing anything.
Original signature : void osvrTimeValueNormalize(OSVR_TimeValue*)

osvrTimeValueSum

public static void osvrTimeValueSum(OSVR_TimeValue tvA,
                                    OSVR_TimeValue tvB)

Sums two time values, replacing the first with the result.

Parameters:

tvA - Destination and first source.

tvB - second source
If a given pointer is NULL, this function returns without doing anything.
Both parameters are expected to be in normalized form.
Original signature : void osvrTimeValueSum(OSVR_TimeValue*, const OSVR_TimeValue*)

osvrTimeValueDifference

public static void osvrTimeValueDifference(OSVR_TimeValue tvA,
                                           OSVR_TimeValue tvB)

Computes the difference between two time values, replacing the first with the result.
Effectively, `*tvA = *tvA - *tvB`

Parameters:

tvA - Destination and first source.

tvB - second source
If a given pointer is NULL, this function returns without doing anything.
Both parameters are expected to be in normalized form.
Original signature : void osvrTimeValueDifference(OSVR_TimeValue*, const OSVR_TimeValue*)

osvrTimeValueCmp

public static int osvrTimeValueCmp(OSVR_TimeValue tvA,
                                   OSVR_TimeValue tvB)

Compares two time values (assumed to be normalized), returning the same values as strcmp

Returns:

<0 if A is earlier than B, 0 if they are the same, and >0 if A
is later than B.
Original signature : int osvrTimeValueCmp(const OSVR_TimeValue*, const OSVR_TimeValue*)

osvrTimeValueDurationSeconds

public static double osvrTimeValueDurationSeconds(OSVR_TimeValue tvA,
                                                  OSVR_TimeValue tvB)

Compute the difference between the two time values, returning the duration as a double-precision floating-point number of seconds.
Effectively, `ret = *tvA - *tvB`

Parameters:

tvA - first source.

tvB - second source

Returns:

Duration of timespan in seconds (floating-point)
Original signature : double osvrTimeValueDurationSeconds(const OSVR_TimeValue*, const OSVR_TimeValue*)

osvrTimeValueGreater

public static byte osvrTimeValueGreater(OSVR_TimeValue tvA,
                                        OSVR_TimeValue tvB)

True if A is later than B. Original signature : OSVR_CBool osvrTimeValueGreater(const OSVR_TimeValue*, const OSVR_TimeValue*)

osvrTimeValueIsNormalized

public static byte osvrTimeValueIsNormalized(OSVR_TimeValue tv)

Returns true if the time value is normalized. Typically used in assertions.
Original signature : bool osvrTimeValueIsNormalized(const OSVR_TimeValue&)

operatorGreater

public static byte operatorGreater(OSVR_TimeValue tvA,
                                   OSVR_TimeValue tvB)

Operator > overload for time values
Original signature : bool operator>(const OSVR_TimeValue&, const OSVR_TimeValue&)

operatorIsEqual

public static byte operatorIsEqual(OSVR_TimeValue tvA,
                                   OSVR_TimeValue tvB)

Operator == overload for time values
Original signature : bool operator==(const OSVR_TimeValue&, const OSVR_TimeValue&)
