Method Detail

elapsed	back to summary
public static long elapsed(long beginNanoTime, long endNanoTime) Calculates the nanoseconds elapsed between two nanoTimes. Parameters beginNanoTime:long the begin nanoTime endNanoTime:long the end nanoTime Returns:long the nanoseconds elapsed

elapsed

back to summary

public static long elapsed(long beginNanoTime, long endNanoTime)

Calculates the nanoseconds elapsed between two nanoTimes.

isBefore back to summary

isBefore	back to summary
public static boolean isBefore(long nanoTime1, long nanoTime2) Returns whether the first nanoTime is strictly before the second nanoTime. Reads as: `"is nanoTime1 strictly before nanoTime2?"`. Avoids the common mistake of comparing the 2 nanoTimes with the less-than `<` operator, which cannot be used when comparing nanoTimes, as specified in `System#nanoTime()`. Parameters nanoTime1:long the first nanoTime nanoTime2:long the second nanoTime Returns:boolean whether the first nanoTime is strictly before the second nanoTime See Also `isBeforeOrSame(long, long)`
