示例1: test_portgraph_clear
# 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_edges [as 別名]
def test_portgraph_clear():
pg = PortGraph()
vid1 = pg.add_vertex()
vid2 = pg.add_vertex()
pid1 = pg.add_in_port(vid1, "in")
pid2 = pg.add_out_port(vid2, "out")
pg.connect(pid2, pid1)
pg.clear()
assert pg.nb_vertices() == 0
assert pg.nb_edges() == 0
assert len(tuple(pg.ports())) == 0示例2: test_portgraph_init
# 需要導入模塊: from openalea.workflow.port_graph import PortGraph [as 別名]
