Class LineageEdge

Object

gudusoft.gsqlparser.ir.semantic.LineageEdge

public final class LineageEdge
extends Object

Single-hop edge: getFrom() depends on getTo().

Edges are intentionally single-hop so a consumer can reconstruct the full provenance graph by chasing them. Transitive output→base-table lineage is computable from these edges; the reverse is not, so the IR keeps the boundary information.
