 LsaDecoder (OspfTypes::Version version)

LsaDecoder

 ~LsaDecoder ()

~LsaDecoder

void  register_decoder (Lsa *lsa)

register_decoder

Register the LSA decoders, called multiple times with each LSA.

Parameters:

LSAdecoder
void  register_unknown_decoder (Lsa *lsa)

register_unknown_decoder

Register the unknown LSA decoder, called once.

Parameters:

LSAdecoder
Lsa::LsaRef  decode (uint8_t *ptr, size_t& len)
throw(InvalidPacket)

decode

[const]

Decode an LSA.

Parameters:

bufpointer to buffer.
lenlength of the buffer on input set to the number of bytes consumed on output.

Returns: A reference to an LSA that manages its own memory.

size_t  min_length ()

min_length

[const]

Returns: The length of the smallest LSA that can be decoded.

bool  validate (uint16_t type)

validate

[const]

Validate type field. If we know how to decode an LSA of this type we must know how to process it.

Returns: true if we know about this type of LSA.

bool  external (uint16_t type)

external

Is an LSA of this type an AS-external-LSA?

Returns: true if this type is an AS-external-LSA

const char * name (uint16_t type)

name

[const]

Return the name of this LSA.

OspfTypes::Version  get_version ()
