Field Summary

protected long	m_part1
protected long	m_part2

Constructor Summary

Guid()
This Constructor creates a new Guid with a new value.

Guid(int part1_high, int part1_low, int part2_high, int part2_low)
This Constructor should not be used anymore because it is slower.

Guid(long part1, long part2)
Hint for programmers: You can enter a long value in your coding in the following way: long l = 123456789L

Constructor Detail

            long part2)

Hint for programmers: You can enter a long value in your coding in the following way:

long l = 123456789L

Guid

public Guid()

This Constructor creates a new Guid with a new value. ...to be honest: The Guid is assembled out of a random value and a time stamp. If this is not "unique enough" then please find the Guid on your own and use the other constructors...

Guid

public Guid(int part1_high,
            int part1_low,
            int part2_high,
            int part2_low)

This Constructor should not be used anymore because it is slower.
