Public Member Functions
	Uuid ()
	Creates the null UUID.
	Uuid (const ValueType *theData)
	Creates a UUID with the values specified by the parameter. The function assumes theData contains 16 bytes and initializes the object with the values of these 16 bytes.
	Uuid (DataType theData)
const DataType &	Data () const
bool	IsNull () const
	operator bool () const
std::string	ToString () const
	Returns the string representation of this UUID. The string representation of a uuid is "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" where 'x' is a hexidecimal digit.

Static Public Member Functions
static Uuid	FromString (const std::string &theStr)
	Creates a UUID object from a string. String must be formatted as five hex fields separated by '-', e.g., "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}" where each 'x' is a hexidecimal digit. The curly braces shown here are optional. If the conversion fails, a null UUID is returned.

CreateRandom()

Uuid cadex::Uuid::CreateRandom ( )

static

Creates new random uuid. This method is thread-safe and uses mutex to syncrhonize access to random number generator.

IsNull()

bool cadex::Uuid::IsNull

(

)

const

Returns true if this is the null UUID {00000000-0000-0000-0000-000000000000}; otherwise returns false.
