Class RelationSource

Object

gudusoft.gsqlparser.ir.semantic.RelationSource

public final class RelationSource
extends Object

One visible relation source in a statement's scope. alias is non-null and defaults to the table name when the SQL omits an alias, so consumers always have a stable local handle to use in ColumnRef.getRelationAlias().

For most kinds (TABLE / CTE / SUBQUERY / UNION) the source is a FROM-clause entry on this statement. For RelationKind.OUTER_REFERENCE (slice 14) the source is synthesised by the builder to record an alias that actually belongs to an enclosing scope's FROM clause; the inner statement carries it so ColumnRef.getRelationAlias() resolves uniformly without needing an explicit "is-outer" flag.
