Method Detail

run

public static StopwatchSample[] run(int warmupRuns,
                    int measuredRuns,
                    BenchmarkUtils.Task... tasks)

Runs the list of tasks to be benchmarked and returns StopwatchSample array with measured results. Number of warmup runs (without measuring) and measured runs must be specified. BenchmarkUtils.Task provides the name of the Stopwatch that will store results.

Tasks should not be extremely short - see BenchmarkUtils.Task javadoc for more.

Parameters:

warmupRuns - number of runs before the measuring starts

measuredRuns - number of measured runs

tasks - list of tasks to measure

Returns:

result of the measured runs as an array of stopwatch objects in the order of the tasks
