Class QuestionBlockGenerator

java.lang.Object

org.ek9lang.compiler.phase7.QuestionBlockGenerator

All Implemented Interfaces:

Function<ExprProcessingDetails,List<IRInstr>>

public final class QuestionBlockGenerator
extends Object
implements Function<ExprProcessingDetails,List<IRInstr>>

Generates IR instructions for question operator (?) using unified SWITCH_CHAIN_BLOCK.

This generator has been migrated to use the unified control flow approach: 1. Delegates to ControlFlowChainGenerator for actual IR generation 2. Maintains backward compatibility with existing call sites 3. Uses CONTROL_FLOW_CHAIN with QUESTION_OPERATOR chain type

The Question operator becomes a simple two-case CONTROL_FLOW_CHAIN: - Case 1: if (operand == null) return Boolean(false) - Default: else return operand._isSet()

createQuestionBlockForVariable

public List<IRInstr> createQuestionBlockForVariable(ISymbol variableSymbol,
 String resultName,
 BasicDetails basicDetails)

Create QUESTION_BLOCK for a variable symbol (used by guarded assignment composition). This method enables composition by allowing other generators to reuse the core question operator logic for variable-based null-safety checking.
