System.GUID

Declaration

type GUID = array(11: PosInt)
constructor GUID(D1: System.UInt32, D2 & D3: System.UInt16, D4: System.UInt64) = \built-in\
converter GUID(Value: any(string, sizeint(False, 128), array(16: System.UInt8))) = \built-in\

Description

The GUID type in the System package is used to store GUIDs in MFL. It is basically a 128-bit integer, stored in an array consisting of one unsigned 32-bit, two unsigned 16-bit and one unsigned 64-bit integer numbers.

Constructor

System.GUID has a built-in constructor that builds a GUID value from its one 32-, two 16- and one 64-bit unsigned integer components. They are mapped uppon the byte array (the actual GUID) as follows:

| Byte        | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
|-------------|---'---'---'---|---'---|---'---|---'---'---'---'---'---'---'---|
| Constructor | D1            | D2    | D3    | D4                            |
'-------------'---------------'-------'-------'-------------------------------'
