Class Transformation

Object

gudusoft.gsqlparser.lineage2.contract.Transformation

public final class Transformation
extends Object

Contract Transformation (lineage2-contract.md §4.2, D-08): original expression text, normalized form (FINGERPRINT-V1 normalization family), SHA-256 of the normalized form, and the location of the original expression in the unit (the normalized form is a canonical rewrite and intentionally has no coordinates).

Unlike Endpoint, the JSON form always carries both the sourceLocation and locationNullReason keys (one of the two is null) — the gold-fixture-pinned shape.

Internal API: not part of the public gsqlparser surface.
