Class SQLEnvCatalogLoader

Object

gudusoft.gsqlparser.sqlenv.compat.SQLEnvCatalogLoader

public final class SQLEnvCatalogLoader
extends Object

Eager bridge facade: walks a UnifiedCatalogModel and writes every catalog/schema/ table/view/routine into a TSQLEnv via the existing public mutation API.

Plan §8.2 / §12 (T1C.2). Per spike T0.3 inventory the loader uses only public TSQLEnv mutation methods and the public catalog-tree API (TSQLEnv.getSQLCatalog(java.lang.String, boolean), TSQLCatalog.getSchema(java.lang.String, boolean), TSQLSchema.createTable(java.lang.String), etc.) — no reflection, no private-field access. The catalog-tree path mirrors SqlflowSQLEnv so schema-less dialects (MySQL, where TSQLEnv.supportSchema(EDbVendor) is false) route through TSQLEnv.DEFAULT_SCHEMA_NAME the same way the legacy loader does.

Sequences are not modeled in TSQLEnv (no dotSequence member of ESQLDataObjectType); they are represented in the runtime layer instead. The loader records an INFO diagnostic for each skipped sequence so callers can correlate the gap.

Method Detail

loadIntoSQLEnv

public CatalogLoadResult loadIntoSQLEnv(TSQLEnv env,
                                        UnifiedCatalogModel model,
                                        CatalogLoadOptions options)

Walk model and apply it to env. Validation runs first; default mode fails on ERROR-severity diagnostics and strict mode also fails on WARN, matching DefaultCatalogLoader (plan §15).

On a validation failure this method throws CatalogException carrying the counts of ERROR / WARN diagnostics — CatalogLoadResult is only returned on success. This matches CatalogLoaders.DefaultCatalogLoader.load(...); the sink (when set on options) still receives every diagnostic before the exception fires so callers can correlate. On non-validation success the returned result carries the populated env plus any informational diagnostics emitted by the loader (e.g. unrepresented sequences).

loadToSQLEnv

public TSQLEnv loadToSQLEnv(UnifiedCatalogModel model,
                            CatalogLoadOptions options)

Convenience: spin up a fresh TSQLEnv (concrete TDDLSQLEnv subclass with empty defaults) and apply model to it. Throws CatalogException on failure to match DefaultCatalogLoader.load(...) semantics.
