Unigine::UGUID Class

UGUID Class

Members

---

static UGUIDPtr create ( )

Default constructor. Creates an empty 0-filled UGUID.

static UGUIDPtr create ( 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.

static UGUIDPtr create ( 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.

unsigned int hash( )

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.

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.

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.
