UGUID ( ) #

Default constructor. Creates an empty 0-filled UGUID.

UGUID ( string str ) #

Constructor. Creates a UGUID from the given source string. UGUID is generated using the SHA1 algorithm.

Arguments

• string str - Source string.

UGUID ( UGUID guid ) #

Copy constructor. Creates a UGUID by copying a source UGUID.

Arguments

• UGUID guid - Source UGUID.

void Generate ( ) #

Generates a new random UGUID value.

void Generate ( string str ) #

Generates a UGUID value from the given source string using the SHA1 algorithm.

Arguments

• string str - Source string.

void Generate ( int& seed_ ) #

Generates a random UGUID value using the seed value.

Arguments

• int& seed_ - Seed value.

void Generate ( const void* data, int size ) #

Generates a UGUID value from the given source byte array of the specified size using the SHA1 algorithm.

Arguments

• const void* data - Source byte array.
• int size - Number of bytes to be taken from the byte array for UGUID generation.

uint GetHashCode ( ) #

Returns a hash for the UGUID value.

Return value

Hash generated for the UGUID value.

void Clear ( ) #

Clears the UGUID value. All 40 bytes are set to 0.

bool IsEmpty ( ) #

Returns a value indicating if the UGUID is empty (all 40 bytes are equal to 0).

Return value

true if the UGUID is empty; otherwise, false.

bool IsValid ( ) #

Returns a value indicating if the UGUID has a valid value.

Return value

true if the value is valid; otherwise, false.

void SetString ( string str ) #

Sets the UGUID value equal to a given 40-character hexadecimal string.

Arguments

• string str - 40-character hexadecimal string representing the UGUID value.

string GetString ( ) #

Returns the UGUID value as a 40-character hexadecimal string.

Return value

40-character hexadecimal string representing the UGUID value.
