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. RESPONSIBILITY: Call increment/decrement operator which mutates the counter in place. REUSABILITY: ALL loop generators (for, while with increment).

The ++ and -- operators in EK9 are MUTATING operators that return VOID. They modify the target object in place - no return value, no assignment needed.

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

public IncrementEvaluator(CallDetailsBuilder callDetailsBuilder)

Method Details

apply

public List<IRInstr> apply(IncrementParams params)

Evaluate increment/decrement on the counter variable.

The ++ and -- operators mutate the target in place and return void. No result storage is needed - the counter variable is modified directly.

Specified by:

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

Parameters:

params - Increment parameters

Returns:

Instructions that mutate the counter variable in place
