UGUID Class

Members

---

UGUID ( ) #

Default constructor. Creates an empty 0-filled UGUID.

UGUID ( const char * str ) #

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

Arguments

• const char * str - Source string.

UGUID ( unsigned char value_ ) #

Arguments

• unsigned char value_ - Source character.

UGUID ( const UGUID & guid ) #

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

Arguments

• const UGUID & guid - Source UGUID.

void generate ( ) #

Generates a new random UGUID value.

void generate ( const char * str ) #

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

Arguments

• const char * 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.

unsigned int hash ( ) #

Returns a hash for the UGUID value.

Return value

Hash generated for the UGUID value.

unsigned long long hashLong ( ) const#

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 ( ) const#

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 ( ) const#

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

Return value

true if the value is valid; otherwise, false.

void setFileSystemString ( const char * str ) #

Sets the string containing the UGUID value with the filesystem prefix "guid://".

Arguments

• const char * str - UGUID value with the filesystem prefix "guid://" to be set.

const char * getFileSystemString ( ) #

Returns the string containing the UGUID value with the filesystem prefix "guid://".

Return value

UGUID value with the filesystem prefix "guid://".

void setString ( const char * str ) #

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

Arguments

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

const char * getString ( ) #

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

Return value

40-character hexadecimal string representing the UGUID value.

UGUID & operator= ( const char * str ) #

Performs UGUID assignment. The value of the destination UGUID is set equal to the source hexadecimal string.

Arguments

• const char * str - Source string. A 40-character hexadecimal string representing the UGUID value.

Return value

Result.

UGUID & operator= ( const UGUID & g ) #

Performs UGUID assignment. Destination UGUID = Source UGUID.

Arguments

• const UGUID & g - Source UGUID.

Return value

Result.

int operator> ( const UGUID & g ) #

Indicates whether the UGUID value is greater than the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is greater than the source UGUID value; otherwise, 0.

int operator>= ( const UGUID & g ) #

Indicates whether the UGUID value is greater than or equal to the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is greater than or equal to the source UGUID value; otherwise, 0.

int operator< ( const UGUID & g ) #

Indicates whether the UGUID value is less than the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is less than or equal to the source UGUID value; otherwise, 0.

int operator<= ( const UGUID & g ) #

Indicates whether the UGUID value is less than or equal to the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is less than or equal to the source UGUID value; otherwise, 0.

int operator== ( const UGUID & g ) #

Equality. Indicates whether the UGUID value is equal to the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is equal to the source UGUID value; otherwise, 0.

int operator!= ( const UGUID & g ) #

Inequality. Indicates whether the UGUID value is not equal to the source UGUID value.

Arguments

• const UGUID & g - Source UGUID.

Return value

1 if the UGUID value is not equal to the source UGUID value; otherwise, 0.

const char * get ( ) #

Returns the UGUID value as a string.

Return value

String.

char & get ( int index ) #

Returns a UGUID character by index.

Arguments

• int index - Index of the character

Return value
