Class ComparisonEvaluator

java.lang.Object

org.ek9lang.compiler.phase7.support.ComparisonEvaluator

All Implemented Interfaces:

Function<ComparisonParams, List<IRInstr>>

public final class ComparisonEvaluator
extends Object
implements Function<ComparisonParams, List<IRInstr>>

CONCERN: Comparison evaluation with boolean primitive extraction. RESPONSIBILITY: Compare two values and extract primitive boolean result. REUSABILITY: ALL control flow generators needing comparison conditions.

Composite helper that combines: 1. BinaryOperatorInvoker (for comparison operator call) 2. PrimitiveBooleanExtractor (for UNBOX to primitive boolean)

This pattern appears in: - ForStatementGenerator (loop condition checks) - WhileStatementGenerator (loop condition) - IfStatementGenerator (conditional evaluation) - SwitchStatementGenerator (case comparisons)

 PrimitiveBooleanExtractor primitiveBooleanExtractor)

Method Details

apply

public List<IRInstr> apply(ComparisonParams params)

Evaluate comparison and extract primitive boolean.

Handles: 1. Binary operator invocation (e.g., "<", "<=", ">", ">=", "==") 2. UNBOX of EK9 Boolean result to primitive boolean 3. Memory management for both operations

Specified by:

apply in interface Function<ComparisonParams, List<IRInstr>>

Parameters:

params - Comparison parameters

Returns:

Instructions ending with primitive boolean in params.primitiveBooleanTemp()
