Class JsonManifestCatalogInputReader

Object

gudusoft.gsqlparser.catalog.input.readers.JsonManifestCatalogInputReader

All Implemented Interfaces:

CatalogInputReader

public final class JsonManifestCatalogInputReader
extends Object
implements CatalogInputReader

Reader for CatalogInputKind.JSON_MANIFEST sources. Parses a JSON document into UnifiedCatalogModel via JSON.parseObject(String) (the in-tree gudusoft.gsqlparser.util.json, no new compile-scope dependency — see spike docs/designs/catalog-input-interface-spikes/json-dependency.md).

The reader walks the parsed Map/List tree manually rather than using reflection-based mapping. Builders apply per-field validation; missing required fields fail with CatalogInputException; unknown fields are tolerated for forward compatibility with manifests that add new keys.

Manifest schema (key fields, top-level keys are case-sensitive):

 {
   "apiVersion": "1",                    // optional, defaults to "1"
   "vendor": "oracle",                   // required; matches EDbVendor name with or
                                         // without the "dbv" prefix (case-insensitive)
   "source": { "name": "...", "readMillis": 0 },
   "identifier": { ...IdentifierConfig fields... },
   "defaults": { "catalog": "...", "schema": "...", "server": "..." },
   "catalogs": [
     { "name": "...", "schemas": [
         { "name": "...",
           "tables":     [{ "name": "...", "columns": [...], "constraints": [...],
                            "indexes": [...], "properties": {} }],
           "views":      [{ "name": "...", "definition": "...",
                            "materialized": false, "columns": [...] }],
           "routines":   [{ "name": "...", "kind": "FUNCTION|PROCEDURE|PACKAGE|ROUTINE",
                            "returns": "...", "parameters": [...] }],
           "synonyms":   [{ "name": "...", "target": "schema.object" }],
           "sequences":  [{ "name": "...", "startsWith": 1, "incrementBy": 1 }]
         }
     ]}
   ]
