mate_query.cpg.models.core.node module

Core node models and functions.

At runtime, the models here are accessed via attributes on a CPG, not directly.

class mate_query.cpg.models.core.node.BaseNode

Bases: mate_query.cpg.models.core.base.Base

classmethod edge_relationship(edge_kind: EdgeKind, other: Type[Node], direction: Optional[Direction] = None, **kwargs: Any) → RelationshipProperty
Parameters
Return type

RelationshipProperty

classmethod from_dirpath(dirpath: str) → List[Node]

Returns Nodes whose debug symbols contain a filepath that includes the given dirpath.

Parameters

dirpath (str) –

Return type

List[Node]

classmethod from_filename_line_no(filepath: str, line_no: Optional[int] = None) → Node

Returns Nodes whose debug symbols contain the given filepath, or the matching filepath and line number.

Parameters

  • filepath (str) –

  • line_no (Optional[int]) –

Return type

Node
