示例1: test_portgraph_remove_vertex
# 需要導入模塊: from openalea.workflow.port_graph import PortGraph [as 別名]
# 或者: from openalea.workflow.port_graph.PortGraph import nb_neighbors [as 別名]

pid2 = pg.add_out_port(vid2, "out")
pg.connect(pid2, pid1)
assert_raises(InvalidVertex, lambda: pg.remove_vertex(vid1 + vid2 + 1))
pg.remove_vertex(vid1)
assert tuple(pg.ports()) == (pid2,)
assert_raises(InvalidVertex, lambda: pg.ports(vid1).next())
assert tuple(pg.ports(vid2)) == (pid2,)
assert pg.nb_connections(pid2) == 0
assert pg.nb_neighbors(vid2) == 0
