Class QueryBlockScope

Object

gudusoft.gsqlparser.ir.semantic.joinanalysis.QueryBlockScope

public final class QueryBlockScope
extends Object

Lexical scope metadata for one query block (GAP 4). Records the block's stable statementIndex (its position in the flat SemanticProgram.getStatements() list), the parentStatementIndex of its lexical owner (null for the main block; CTE reference sites are not parent edges), the ScopeKind, an optional name (e.g. a CTE name), and an optional span.

Immutable. Introduced by join-analysis slice 162 (S1); populated in slice 170 (S9).
