UGUID Class
This class represents a globally unique identifier (a 40-byte hash value). The SHA1 algorithm is used for hash generation.
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 ( 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 clear ( ) #
Clears the UGUID value. All 40 bytes are set to 0.int isEmpty ( ) #
Returns a value indicating if the UGUID is empty (all 40 bytes are equal to 0).Return value
1 if the UGUID is empty; otherwise, 0.int isValid ( ) #
Returns a value indicating if the UGUID has a valid value.Return value
1 if the value is valid; otherwise, 0.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.Last update:
