Class ContractEdge

Object

gudusoft.gsqlparser.lineage2.contract.ContractEdge

public final class ContractEdge
extends Object

Contract Edge (lineage2-contract.md §4) — the atomic lineage assertion: source endpoint influences target endpoint in manner role.

source is nullable exclusively for role: DERIVED (constant-only / synthesized targets); the identity layer treats a null source as empty strings for all source components per rev-3 normalization. rowLevel is derived: true iff axis == ROW.

Internal API: not part of the public gsqlparser surface.
