Class LazyCatalogSqlEnv

Object

gudusoft.gsqlparser.sqlenv.compat.LazyCatalogSqlEnv

public final class LazyCatalogSqlEnv
extends Object

Convenience facade aliasing CatalogRuntimeToSQLEnvBridge for the lazy-mode use case. Plan §13.3.

Two flavors:

• from(CatalogRuntime) — wrap an already-built runtime as a TSQLEnv that the legacy parser can consume.
• from(CatalogProvider, CatalogProviderConfig) — open the provider, build a CatalogRuntime in LAZY mode, and wrap. Vendor is read from the provider through a one-shot empty snapshot to keep the facade ergonomic for callers that don't already have a runtime in hand.

Both flavors carry no CatalogLoadOptions; callers that need defaults (active catalog/schema, fetch caps, identifier overrides) should construct the CatalogRuntimeToSQLEnvBridge directly with their CatalogLoadOptions instead.

Method Summary

Modifier and Type	Method and Description
static TSQLEnv	from(CatalogProvider provider, CatalogProviderConfig config) Open the provider, build a runtime in LAZY mode at vendor generic, and wrap.
static TSQLEnv	from(CatalogProvider provider, CatalogProviderConfig config, EDbVendor vendor) Open the provider, build a runtime in LAZY mode for the given vendor, and wrap.
static TSQLEnv	from(CatalogRuntime runtime) Wrap an existing runtime as a TSQLEnv.
static TSQLEnv	from(CatalogRuntime runtime, CatalogLoadOptions options) Wrap an existing runtime as a TSQLEnv with the supplied options applied (defaults / identifier config / fetch caps).

Method Detail

from

public static TSQLEnv from(CatalogRuntime runtime)

Wrap an existing runtime as a TSQLEnv. The runtime owns its provider.

from

public static TSQLEnv from(CatalogRuntime runtime,
                           CatalogLoadOptions options)

Wrap an existing runtime as a TSQLEnv with the supplied options applied (defaults / identifier config / fetch caps). Convenience for callers that already have a CatalogLoadOptions in hand.

from

public static TSQLEnv from(CatalogProvider provider,
                           CatalogProviderConfig config)

Open the provider, build a runtime in LAZY mode at vendor generic, and wrap. Mirrors CatalogLoaders.fromProvider(CatalogProvider, CatalogProviderConfig) — see that method's Javadoc for why the default vendor is generic. Most callers want from(CatalogProvider, CatalogProviderConfig, EDbVendor) instead.

from

public static TSQLEnv from(CatalogProvider provider,
                           CatalogProviderConfig config,
                           EDbVendor vendor)

Open the provider, build a runtime in LAZY mode for the given vendor, and wrap. The vendor-explicit form is preferred when the caller knows it: identifier folding and resolver candidate-expansion both rely on the runtime's vendor.
