Class QuestionBlockGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.QuestionBlockGenerator

All Implemented Interfaces:

Function<ExprProcessingDetails, List<IRInstr>>

public final class QuestionBlockGenerator
extends AbstractGenerator
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 injected 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()

PHASE 7 REFACTORING COMPLETE: Now accepts injected ControlFlowChainGenerator for maximum object reuse.
