Interface NanoSampler

All Known Implementing Classes:

Histogram, RecordingHistogram

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface NanoSampler

The NanoSampler interface provides a contract for recording samples where the duration of each sample is measured in nanoseconds. It is a functional interface, meaning it is intended to be used with lambda expressions or method references.

Classes implementing this interface, such as Histogram, should record samples with nanosecond precision.

The NanoSampler interface is marked as SingleThreaded, indicating that implementations are not thread-safe and must only be accessed by a single thread at a time.

Method Summary

Modifier and Type	Method and Description
void	sampleNanos(long durationNs) Records a sample with the provided duration in nanoseconds.

Method Detail

sampleNanos

void sampleNanos(long durationNs)

Records a sample with the provided duration in nanoseconds.

This method must be called from a single thread only. If called from multiple threads or if provided with a negative duration, the result is unspecified and no errors or exceptions should be thrown.

Parameters:

durationNs - The duration of the sample in nanoseconds. Must be non-negative.
