genplanner.ZoneRelationMatrix

class genplanner.ZoneRelationMatrix(zones, _m)

Symmetric matrix of relations between zones. Access is O(1). Default relation is NEUTRAL.

Symmetry invariant:

_m[a][b] == _m[b][a] for all a,b

Parameters:

• zones (tuple[Zone, ...])

• _m (dict[Zone, dict[Zone, Relation]])

__init__(zones, _m)

Parameters:

• zones (tuple[Zone, ...])

• _m (dict[Zone, dict[Zone, Relation]])

Return type:

None

Methods

__init__(zones, _m)
as_dataframe()	Returns a DataFrame with Zone objects as both index and columns.
empty(zones[, default])
from_dataframe(df, *[, value_map, default, ...])	df must be square.
from_kind_forbidden(zones, kind_forbidden, *)
from_pairs(zones, *[, neighbors, forbidden, ...])	Build from explicit pairs.
get(a, b)
is_forbidden(a, b)
is_neighbor(a, b)
subset(zones, *[, strict])	Return a new matrix restricted to the provided zones (if present in this matrix).
to_pretty_string(*[, name_width, ...])
with_pairs(pairs, rel)	Applies pairs and enforces symmetry: (a,b) and (b,a) both set to rel.
zone_forbidden()
zone_neighbors()
