Class SwitchStatementGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.SwitchStatementGenerator

All Implemented Interfaces:

Function<EK9Parser.SwitchStatementExpressionContext, List<IRInstr>>

public final class SwitchStatementGenerator
extends AbstractGenerator
implements Function<EK9Parser.SwitchStatementExpressionContext, List<IRInstr>>

Generates IR for switch statements (statement form only) using CONTROL_FLOW_CHAIN. Follows the same pattern as IfStatementGenerator.

Current implementation supports: - Literal case comparisons (case 1, case 2, etc.) - Integer type evaluation variable - Default case - Statement form only (no return value)

NOT yet supported: - Expression form (switch as expression returning value) - Guard variables in switch - Enum case comparisons - Multiple literals per case (case 1, 2, 3) - Expression cases (case < 12, case > 50)
