Interface Stopwatch.StopwatchSet

All Superinterfaces:

Stopwatch.Durations

Enclosing class:

Stopwatch

@ThreadSafe
public static interface Stopwatch.StopwatchSet
extends Stopwatch.Durations

A set of stopwatches whose durations are combined. New stopwatches can be created at any time, and when Stopwatch.stop() will always record their duration with this set.

This set is threadsafe, meaning that multiple threads can create() new stopwatches concurrently, and each stopwatch's duration is measured separately. Additionally, all of the other methods of this interface are also threadsafe.

Method Summary

Modifier and Type	Method and Description
void	await() Block until all running stopwatches have been stopped.
void	await(long timeout, TimeUnit unit) Block until all stopwatches that have been created and started are stopped.
Stopwatch	create() Create a new stopwatch that records durations with this set.
default <T> T	time(Callable<T> runnable) Time the given function.
default <T> void	time(int repeat, Callable<T> runnable, Consumer<T> cleanup) Time the given function multiple times.
default void	time(int repeat, Runnable runnable) Time the given function multiple times.
default void	time(Runnable runnable) Time the given function.

Method Detail

create

Stopwatch create()

Create a new stopwatch that records durations with this set.

Returns:

the new stopwatch; never null

time

default void time(Runnable runnable)

Time the given function.

Parameters:

runnable - the function to call

time

default <T> T time(Callable<T> runnable)

Time the given function.

Parameters:

runnable - the function that is to be executed; may not be null

Returns:

the result of the operation

time

default void time(int repeat,
                  Runnable runnable)

Time the given function multiple times.

Parameters:

repeat - the number of times to repeat the function call; must be positive

runnable - the function to call; may not be null

time

default <T> void time(int repeat,
                      Callable<T> runnable,
                      Consumer<T> cleanup)
               throws Exception

Time the given function multiple times.

Parameters:

repeat - the number of times to repeat the function call; must be positive

runnable - the function that is to be executed a number of times; may not be null

cleanup - the function that is to be called after each time call to the runnable function, and not included in the time measurements; may be null

Throws:

Exception - the exception thrown by the runnable function

await

void await()
    throws InterruptedException

Block until all running stopwatches have been stopped. This means that if a stopwatch is created but never started, this method will not wait for it. Likewise, if a stopwatch is created and started, then this method will block until the stopwatch is stopped (even if the same stopwatch is started multiple times). are stopped.

Throws:

InterruptedException - if the thread is interrupted before unblocking

await

void await(long timeout,
           TimeUnit unit)
    throws InterruptedException

Block until all stopwatches that have been created and started are stopped.

Parameters:

timeout - the maximum length of time that this method should block

unit - the unit for the timeout; may not be null

Throws:

InterruptedException - if the thread is interrupted before unblocking
