Member Function Documentation

fromText()

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.

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:

getClientId()

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

MAX_CLIENT_ID_LEN

size_t isc::dhcp::ClientId::MAX_CLIENT_ID_LEN = IdentifierType::getMaxSize()

staticconstexpr

Maximum size of a client ID.

Note

RFC 2131 does not specify an upper length of a client ID, but the byte used to specify the option size byte can only go up to 255.

Definition at line 235 of file duid.h.

MIN_CLIENT_ID_LEN

size_t isc::dhcp::ClientId::MIN_CLIENT_ID_LEN = IdentifierType::getMinSize()

staticconstexpr

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.
