Class: Conditional

Defined in: packages/core/src/plan/operators/item/conditional.ts:12

A CASE / IF-THEN-ELSE expression: evaluates condition (if present), matches against whenThens in order, and falls back to defaultCase.

Implements

• PlanOperator

Constructors

Constructor

new Conditional(lang, condition, whenThens, defaultCase): Conditional

Defined in: packages/core/src/plan/operators/item/conditional.ts:16

Parameters

Parameter	Type	Description
lang	Lowercase<string>	PlanOperator.lang
condition	PlanOperator | ASTIdentifier	Searched-CASE operand; null for a simple CASE without a common operand.
whenThens	[PlanOperator | ASTIdentifier, PlanOperator | ASTIdentifier][]	Ordered list of [WHEN, THEN] pairs.
defaultCase	PlanOperator | ASTIdentifier	The ELSE expression; null means return null when no branch matches.

Returns

Conditional
