Chain link for a DiagramTag. A link is a tuple + vertex id + depth,
with a comparison operator defined
|
__init__(self,
objects,
vertex_id=None)
Initialize, either with a tuple of DiagramTagChainLinks and a
vertex_id (defined by DiagramTag.vertex_id_from_vertex), or with an
external leg object (end link) defined by DiagramTag.link_from_leg |

|
get_external_numbers(self)
Get the permutation of external numbers (assumed to be the second
entry in the end link tuples) |

__eq__(self,
other)
For end link, consider equal if self.links[0][0] ==
other.links[0][0], i.e., ignore the leg number (in links[0][1]). |
