推荐导入: from cadflow import GraphSession
签名
class GraphSession(graph_id: 'Optional[str]' = None) -> 'None'
功能说明
GraphSession 是 CadFlow Graph、序列化与重放领域的公共类。
原始 API 说明
Context manager that records CAD operations into a DAG.
Usage::
with GraphSession() as session: n1 = record_operation( "make_line_redge", {"start": (0, 0, 0), "end": (1, 0, 0)} ) n2 = record_operation( "make_line_redge", {"start": (1, 0, 0), "end": (1, 1, 0)} ) record_operation( "make_wire_from_edges_rwire", {"edge_count": 2}, inputs=[n1, n2] )
Access the graph after the session print(session.graph.topological_order())

|---|---|---|---|---|
graph_id | 'Optional[str]' | 否 | None | 源码 Docstring 未单独说明。 |
返回值
类型: 'None'
源码 Docstring 未声明更多返回语义。
异常
源码 Docstring 未声明更窄的异常契约。类型、数值、所有权、路径或后端状态无效时，仍可能抛出相应公共异常。
