Member Function Documentation

CopyLittleEndianTo()

void Arp::System::Commons::Configuration::Uuid::CopyLittleEndianTo

(

byte *

pBuffer

)

const

Copies the binary representation to the given buffer in little endian.

Parameters

pBuffer

The buffer to be filled in little endian format.The count of copied bytes is always 16, thus the as argument passed buffer should have at least a size of 16.

CopyTo()

void Arp::System::Commons::Configuration::Uuid::CopyTo

(

byte *

pBuffer

)

const

Copies the binary representation to the given buffer in big endian.

Parameters

pBuffer

The buffer to be filled in big endian format.The count of copied bytes is always 16, thus the as argument passed buffer should have at least a size of 16.

GetHashValue()

size_t Arp::System::Commons::Configuration::Uuid::GetHashValue

(

void

)

const

Gets the hash value for this uuid.

Returns

The hash value of this uuid.

IsEmpty()

bool Arp::System::Commons::Configuration::Uuid::IsEmpty ( void  ) const

inline

Checks if this uuid is emtpy (zero'ed).

Returns

true if it is empty, otherwise false.

Parse()

static Uuid Arp::System::Commons::Configuration::Uuid::Parse ( const String &  input )

static

Creates a new unique id from the given input string.

Parameters

input

The input string to parse

Exceptions

ArgumentException

If the input string has not a valid UUID format.

The following string formats a supported xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} {xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx}

ToString()

String Arp::System::Commons::Configuration::Uuid::ToString

(

void

)

const

Creates a string representation of this uuid.

Returns

A string of this uuid in the format 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'.

TryParse()

static bool Arp::System::Commons::Configuration::Uuid::TryParse ( const String &  input, Uuid &  result  )

static

Creates a new unique id.

Parameters

input	The input string to parse
result	The resulting uuid.

Returns

true on success, otherwise false.
