LateralColumnAliasRegistry

abstract class LateralColumnAliasRegistry extends AnyRef

Base class for lateral column alias registry. This class is extended by 2 implementations:

  1. LateralColumnAliasRegistryImpl - When SQLConf.LATERAL_COLUMN_ALIAS_IMPLICIT_ENABLED is enabled, this class implements logic for LCA resolution. 2. LateralColumnAliasProhibitedRegistry - Dummy class whose methods throw exceptions when LCA resolution is disabled by SQLConf.LATERAL_COLUMN_ALIAS_IMPLICIT_ENABLED.
