gfc-time

A library that contains time related scala utility classes. Part of the gilt foundation classes.

Contents and Example Usage

Various utilities for timing & reporting on blocks of code and scala Futures.

Format a nanosecond timespan into a human-readable string, like "37 us" or "45 days 08:55:01".

val start = System.nanoTime() doSomething() val elapsed = Timer.pretty(System.nanoTime() - start) println(s"doSomething() took $elapsed")
Report ns result (Long value)

val result = Timer.time(l => println(s"Operation took $l ns")) { // timed function, returning a result }
Report formatted result. The result String is using the best suitable time unit (e.g. "10 ns", "456 ms", "45 days 08:55:01" etc.)

val result = Timer.time(s => println(s"Operation took ${s}")) { // timed function, returning a result }
Time the body, then calls pretty on the elapsed time to get a more human-friendly time String, then passes that to the "format" method.

val result = Timer.time("Operation took %s", println _)) { // timed function, returning a result }
Similar functions as above are available to time scala Future completions.

A immutable lightweight wrapper around a millisecond timestamp.
