Class OraclePackageRegistry

Object

gudusoft.gsqlparser.resolver2.OraclePackageRegistry

public class OraclePackageRegistry
extends Object

Registry for Oracle packages encountered during scope building.

Pre-built during the initial scan of statements to allow:

• Cross-package references (pkg1 references pkg2.constant)
• Spec/body merging for complete member visibility
• O(1) lookup of package namespaces by name

Usage in ScopeBuilder:

 // During build() pre-traversal:
 packageRegistry = new OraclePackageRegistry();
 packageRegistry.buildFromStatements(statements);

 // During visitor traversal (when entering package body):
 OraclePackageNamespace pkgNs = packageRegistry.getPackage(packageName);
