Method Detail

measureDuration

public static <T> Pair<T,Duration> measureDuration(Supplier<T> c)

Measure the duration of the given callable.

Parameters:

c - The callable to measure.

Returns:

A Pair containing the result of c and the duration.

reportDuration

public static <T> CompletableFuture<T> reportDuration(Supplier<CompletableFuture<T>> c,
                                                      MetricCollector metricCollector,
                                                      SdkMetric<Duration> metric)

Report a duration metric of the given CompletableFuture supplier.

Parameters:

c - The callable to measure.

metricCollector - The MetricCollector where the metric is to be reported.

metric - The metric to be reported.

Returns:

A Pair containing the result of c and the duration.

measureDurationUnsafe

public static <T> Pair<T,Duration> measureDurationUnsafe(Callable<T> c)
                                                        throws Exception

Parameters:

c - The callable to measure.

Returns:

A Pair containing the result of c and the duration.

Throws:

Exception
