Detailed Description

Parent class for AsPath elements, which can be either AsSet or AsSequence.

typedef list <AsNum>::iterator iterator

iterator

typedef list <AsNum>::const_iterator const_iterator

const_iterator

typedef list <AsNum>::const_reverse_iterator const_reverse_iterator

const_reverse_iterator

 AsSegment (ASPathSegType t = AS_NONE)

AsSegment

Constructor of an empty AsSegment

 AsSegment (const uint8_t* d)

AsSegment

constructor from external representation will just decode the chunk of data received, and convert to internal representation. In fact, the external representation is quite simple and effective.

_type is d[0], l is d[1], entries follow.

 AsSegment (const AsSegment& a)

AsSegment

Copy constructor

 ~AsSegment ()

~AsSegment

The destructor has nothing to do, the underlying container will take care of the thing.

void  clear ()

clear

reset whatever is currently contained in the object.

size_t  path_length ()

path_length

[const]

Returns: the path length, which is 1 for an AS_SET, and the length of the sequence for an AS_SEQUENCE

size_t  as_size ()

as_size

[const]

void  add_as (const AsNum& n)

add_as

Add AsNum at the end of the segment (order is irrelevant for AS_SET but important for AS_SEQUENCE) This is used when initializing from a string.

void  prepend_as (const AsNum& n)

prepend_as

Add AsNum at the beginning of the segment (order is irrelevant for AS_SET but important for AS_SEQUENCE). This is used e.g. when a node is adding its AsNum to the sequence.

bool  contains (const AsNum& as_num)

contains

[const]

Check if a given AsNum is contained in the segment.

const AsNum&  first_asnum ()

first_asnum

[const]

void  decode (const uint8_t *d)

decode

Convert the external representation into the internal one. _type is d[0], _entries is d[1], entries follow.

const uint8_t * encode (size_t &len, uint8_t *buf)

encode

[const]

Convert from internal to external representation. If we do not pass a buffer (buf = 0), then the routine will allocate a new one; otherwise, len indicates the size of the input buffer, which must be large enough to store the encoding.

Returns: the pointer to the buffer, len is the actual size.

size_t  wire_size ()

wire_size

[const]

Returns: the size of the list on the wire.

string  str ()

str

[const]

Returns: fancy string representation of the segment

string  short_str ()

short_str

[const]

Returns: compact string representation of the segment

bool  operator== (const AsSegment& him)

operator==

[const]

compares internal representations for equality.

bool  operator< (const AsSegment& him)

operator<

[const]

Compares internal representations for <.

ASPathSegType  type ()

type

[const]

void  set_type (ASPathSegType t)

set_type

size_t  encode_for_mib (uint8_t* buf, size_t buf_size)

encode_for_mib

[const]
