gudusoft.gsqlparser.catalog.input.CatalogInputReaders

public final class CatalogInputReaders
extends Object

Look-up table for CatalogInputReaderFactorys registered via META-INF/services/gudusoft.gsqlparser.catalog.input.CatalogInputReaderFactory or programmatically via register(CatalogInputReaderFactory).

Plan §7.1 / §13.1. Process-global registry; lazily initialized from the ServiceLoader; programmatic registration takes precedence on CatalogInputKind collision.
