SqllrResources (General SQL Parser Java Library Core 4.2.19 API)

Object
- gudusoft.gsqlparser.lineage.v2.SqllrResources

```
public final class SqllrResources
extends Object
```
The SQL-LR data files this library ships: the lineage document schema, the core registry, the qualification profiles, the dependency snapshots and the identifier rule sets, at their lineage-spec/ paths under "/gudusoft/gsqlparser/lineage/v2/".
A jar cannot list a directory, so resources.sha256 (in sha256sum format) lists every file with its SHA-256 digest. A file is served only when it is listed, and only when its bytes have that digest. Each file is parsed once with CanonicalJson.parse(byte[]) into an unmodifiable value that every caller shares.

Since:

4.2.17
