Detailed Description

PathAttributeList is used to handle efficiently path attribute lists.

An object in the class is initialized from explicit PathAttribute objects passed in by reference. The initialization creates a copy of the attribute, links it into a list, and for mandatory attributes it also stores a pointer to the newly created attribute into a class member (e.g. _aspath_att ...) for ease of use.

Add this path attribute to the list after making a local copy.

Add this path attribute to the list don't make a local copy.

For unknown attributes: 1) If transitive set the partial bit. 2) If not transitive remove.

Encode the PA List for transmission to the specified peer. Note that as Some peers speak 4-byte AS numbers and some don't, the encoding is peer-specific.

Parameters:

Returns: true if the data was successfully encoded; false if there wasn't enough space in the buffer for the data.
