Member Function Documentation

ClientIdPtr isc::dhcp::ClientId::fromText ( const std::string & text )

static

Create client identifier from the textual format.

This static function creates the instance of the ClientId from the textual format. Internally it calls DUID::fromText. The format of the input must match the format of the DUID in DUID::fromText.

Parameters

text	Client identifier in the textual format.

Returns: Pointer to the instance of the ClientId.

Exceptions

isc::BadValue	if parsing the client identifier failed.
isc::OutOfRange	if the client identifier is truncated.

Here is the call graph for this function:

const std::vector< uint8_t > & isc::dhcp::ClientId::getClientId ( ) const

Returns reference to the client-id data.

Warning: Since this function returns a reference to the vector (not a copy) the returned object must be used with caution because it remains valid only for the time period when the object which returned it is valid.

Returns: A reference to a vector holding a client identifier.

Member Data Documentation

const size_t isc::dhcp::ClientId::MAX_CLIENT_ID_LEN = DUID::MAX_DUID_LEN

static

Maximum size of a client ID.

This is the same as the maximum size of the underlying DUID.

Note: RFC 2131 does not specify an upper length of a client ID, the value chosen here just being that of the underlying DUID. For some backend database, there may be a possible (minor) performance enhancement if this were smaller.

const size_t isc::dhcp::ClientId::MIN_CLIENT_ID_LEN = 2

static

Minimum size of a client ID.

Excerpt from RFC2132, section 9.14. The code for this option is 61, and its minimum length is 2.
