## Detailed Description

Handling 16 Byte Globally Unique Identifiers.

Each interface declares its identifier as static member inside the interface namespace (e.g. FUnknown::iid).

## Member Function Documentation

bool generate | ( |  | ) |

Generates a new Unique Identifier (UID).

Will return true for success. If the return value is false, either no UID is generated or the UID is not guaranteed to be unique worldwide.

bool isValid | ( |  | ) | const

Checks if the UID data is valid.

The default constructor initializes the memory with zeros.

FUID & operator= | ( | const FUID & | f | ) |

|  | uint32 | d4
| ) |  |

void to4Int | ( | uint32 & | d1,
|  | uint32 & | d2,
|  | uint32 & | d3,
|  | uint32 & | d4
| ) |  | const

void toString | ( | char8 * | string | ) | const

Converts UID to a string.

The string will be 32 characters long, representing the hexadecimal values of each data byte (e.g. "9127BE30160E4BB69966670AA6087880").

Typical use-case is:

char8[33] strUID = {0};
FUID uid;
if (uid.generate ())
uid.toString (strUID);

bool fromString | ( | const char8 * | string | ) |

Sets the UID data from a string.

The string has to be 32 characters long, where each character-pair is the ASCII-encoded hexadecimal value of the corresponding data byte.

void toRegistryString | ( | char8 * | string | ) | const

Converts UID to a string in Microsoft(R) OLE format.

(e.g. "{c200e360-38c5-11ce-ae62-08002b2b79ef}")

bool fromRegistryString | ( | const char8 * | string | ) |

Sets the UID data from a string in Microsoft(R) OLE format.

void print | ( | int32 | style,
|  | char8 * | string = `nullptr`,
|  | size_t | stringBufferSize = `0`
| ) |  | const

Prints the UID to a string (or debug output if string is NULL).

Parameters

  style | can be chosen from the FUID::UIDPrintStyle enumeration.
  string | is the output string if not NULL.
  stringBufferSize | is the size of the output string

void print | ( | char8 * | string = `nullptr`,
|  | int32 | style = `kINLINE_UID`
| ) |  | const
