Class InMemoryCatalogSnapshot

Object

gudusoft.gsqlparser.catalog.runtime.InMemoryCatalogSnapshot

All Implemented Interfaces:

CatalogSnapshot

public final class InMemoryCatalogSnapshot
extends Object
implements CatalogSnapshot

In-memory CatalogSnapshot backed by Map<String, CatalogEntry>s keyed via CatalogIdentifierPolicy.keyForMap(CatalogQualifiedName).

Plan §6 / §7.2. The fast path is the kind-segregated keyForMap lookup; on a miss for COLLATION_BASED dialects (MSSQL with case-insensitive collation, MySQL lower_case_table_names=2) the snapshot falls back to a linear scan via CatalogIdentifierPolicy.areEqual(gudusoft.gsqlparser.catalog.runtime.CatalogQualifiedName, gudusoft.gsqlparser.catalog.runtime.CatalogQualifiedName) — same contract as IdentifierService.canUseCompositeKey.

Construction goes through builder(); the snapshot is immutable once built. Children are precomputed at build time so children(CatalogObjectId, CatalogObjectKind) does not walk every entry.
