Class IncrementEvaluator

java.lang.Object

org.ek9lang.compiler.phase7.support.IncrementEvaluator

All Implemented Interfaces:

Function<IncrementParams, List<IRInstr>>

public final class IncrementEvaluator
extends Object
implements Function<IncrementParams, List<IRInstr>>

CONCERN: Loop counter increment/decrement with assignment. RESPONSIBILITY: Call increment/decrement operator and update loop counter. REUSABILITY: ALL loop generators (for, while with increment).

Composite helper that combines: 1. UnaryOperatorInvoker (for ++ or -- operator call) 2. VAR_MOVE assignment (update loop counter)

This pattern appears in: - ForStatementGenerator (loop counter increment/decrement) - WhileStatementGenerator (manual increment patterns)
