Class ForStatementGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.ForStatementGenerator

All Implemented Interfaces:

Function<EK9Parser.ForStatementExpressionContext, List<IRInstr>>

public final class ForStatementGenerator
extends AbstractGenerator
implements Function<EK9Parser.ForStatementExpressionContext, List<IRInstr>>

Coordinates for-statement IR generation by delegating to specialized generators.

Handles two distinct loop types:

• For-range loops (for i in 1..10): Delegates to ForRangeGenerator
• For-in loops (for item in collection): Delegates to ForInGenerator

ARCHITECTURE: Follows ExprInstrGenerator coordinator pattern - thin orchestration layer that delegates complex implementation to focused, specialized generators.

Method Details

apply

public List<IRInstr> apply(EK9Parser.ForStatementExpressionContext ctx)

Main entry point for for-statement IR generation.

Routes to appropriate specialized generator based on loop type: - forLoop() present → for-in loop (iterator-based collection iteration) - forRange() present → for-range loop (polymorphic range iteration) - returningParam() present → expression form (not yet implemented)

Specified by:

apply in interface Function<EK9Parser.ForStatementExpressionContext, List<IRInstr>>

Parameters:

ctx - ForStatementExpressionContext from parser

Returns:

IR instructions for the complete for-statement
