Graph runtime enumerations.

EdgeCastingType

Bases: BaseEnum

Types of edge casting supported.

PAIR: Edges are cast as pairs of vertices PRODUCT: Edges are cast as combinations of vertex sets

EdgeDirection

Bases: BaseEnum

Which orientations a read follows, relative to the anchor vertex.

OUT: anchor is the edge source (the historical, and still default, behaviour) IN: anchor is the edge target ANY: either orientation — the correct reading of a logically undirected edge

Not every backend can answer every value. Reverse reachability is free or cheap on most targets but is fixed at DDL time on TigerGraph; see :mod:graflo.db.edge_direction_support.
