Class DeltaTimestampStrategy

java.lang.Object

com.github.f4b6a3.uuid.timestamp.DeltaTimestampStrategy

All Implemented Interfaces:

TimestampStrategy

public class DeltaTimestampStrategy
extends Object
implements TimestampStrategy

This is an implementation of TimestampStrategy that provides nanosecond resolution. It implements a Clock that simulates a nanoseconds resolution by calculating the difference (delta) between subsequent calls to the method System.nanoTime(). This class provides nanosecond precision, but not necessarily nanosecond resolution. It's slower than NanosecondTimestampStrategy and DefaultTimestampStrategy.
