TimeFunction (uuid-creator 5.3.3 API)

All Superinterfaces:

LongSupplier

All Known Implementing Classes:

DefaultTimeFunction, WindowsTimeFunction

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 TimeFunction
extends LongSupplier
```
Function that must return a number of 100-nanoseconds since 1970-01-01 (Unix epoch).
Example:
```
 // A function that returns `Instant.now()` as a number of 100ns
 TimeFunction f = () -> TimeFunction.toUnixTimestamp(Instant.now());
 
```
In JDK 8, Instant.now() has millisecond precision, in spite of Instant has nanoseconds resolution. In JDK 9+, Instant.now() has microsecond precision.

Method Summary

Static Methods
Modifier and Type	Method	Description
`static long`	`toExpectedRange(long timestamp)`	Clears the leading bits so that the resulting number is in the range 0 to 2^60-1.

- Method Detail
  - toUnixTimestamp
```
static long toUnixTimestamp(Instant instant)
```
    Converts an instant to a number of 100-nanoseconds since 1970-01-01 (Unix epoch).
    
    Parameters:
    
    instant - an instant
    
    Returns:
    
    a number of 100-nanoseconds since 1970-01-01 (Unix epoch)
  - toExpectedRange
```
static long toExpectedRange(long timestamp)
```
    Clears the leading bits so that the resulting number is in the range 0 to 2^60-1.
    The result is equivalent to n % 2^60.
    
    Parameters:
    
    timestamp - a number of 100-nanoseconds since 1970-01-01 (Unix epoch)
    
    Returns:
    
    a number in the range 0 to 2^60-1.
