Class Measure

java.lang.Object

de.galan.commons.util.Measure

public class Measure
extends Object

Measures invokation of Runnables/Callables in milliseconds. Average of n-invocations can also be calculated (using the '.every(n)' builder method). A total can be logged using finish() on the Measure object. Thread-safe.

Method Summary

Modifier and Type	Method and Description
<V> V	call(Callable<V> callable) Measure the invokation time of the given Callable.
Measure	every(Integer iterations) If provided, the average on a single invokation will be calculated/logged after every n-iterations.
void	finish() This method can be called to print the total amount of time taken until that point in time.
static Measure	measure(String what) Builds a new Measure object to measure invokations of runnables/callables.
void	run(ExceptionalRunnable runnable) Measure the invokation time of the given ExceptionalRunnable.
void	runnable(Runnable runnable) Measure the invokation time of the given Runnable (without Exception).
Measure	total(boolean total)
