bhypergraphs 1.0.1

Hypergraphs and DB using hypergraphs

# hypergraphs

Uses:

from bhg import Graph
import time

g = Graph()

st = time.time()

node_types = ['wiki', 'nic', 'mac']
data = [
{'wiki': '101', 'nic': '101--1/0/1', 't1':0, 't2': 1, 'mac':'00-11-22', 'source': 'mac'},
{'wiki': '102', 'nic': '102--1/0/1', 't1':0, 't2': 2, 'mac':'01-11-22', 'source': 'mac'},
{'wiki': '103', 'nic': '103--1/0/1', 't1':0, 't2': 3, 'mac':'02-11-22', 'source': 'mac'},
{'wiki': '101', 'nic': '101--1/0/1', 't1':100, 't2': 1, 'mac':'00-11-22', 'source': 'mac'},
]

g.add_node_types(*node_types)

for ed in data:
n_ids, p = g.separate_keys(ed)
et = p.pop('source')
n = list(g.nodes(**n_ids))
_e = g.edges(*n, type = et)
if not _e:
_e = {Edge(g, type = et, nodes = n, **p)}
else:
for __e in _e:
__e.update(**p)

print(time.time() - st ,'s')

for _e in g._edges:
for __e in g._edges[_e]:
print('t3' in __e)
print(__e.dump_dict())

Uses with db:

from bhg.db import GraphDB, toDictIterator

indexes = ['wiki', 'nic', 'mac']
data = [
{'wiki': '101', 'nic': '101--1/0/1', 't1':0, 'mac':'00-11-22', 'source': 'mac'},
{'wiki': '102', 'nic': '102--1/0/2', 't1':0, 'mac':'00-11-22', 'source': 'mac'},
{'wiki': '103', 'nic': '103--1/0/1', 't1':0, 'mac':'02-11-22', 'source': 'mac'},
{'wiki': '101', 'nic': '101--1/0/1', 't1':100, 'mac':'00-11-22', 'source': 'mac'},
{'wiki': '101', 'nic': '101--1/0/1', 't1':120, 'mac':'00-11-22', 'source': 'mac'},
]

db = GraphDB(indexes)

for d in data:
table = d.pop('source', 'unk')
db.update_or_insert(table, d)

query = db.nodes.filter(nic__endswith = '1/0/1', mac = '00-11-22')

for i in toDictIterator(query.edges):
print(i)
