Class UnaryOperationGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.UnaryOperationGenerator

All Implemented Interfaces:

Function<ExprProcessingDetails, List<IRInstr>>

public final class UnaryOperationGenerator
extends AbstractGenerator
implements Function<ExprProcessingDetails, List<IRInstr>>

Generates IR instructions for unary operations (e.g., unary minus, increment, decrement, etc.).

Handles:
- Operand evaluation with proper memory management
- Cost-based method resolution with automatic promotion
- CallInstr.operator generation for unary method calls

PHASE 7 REFACTORING: Consolidated WithProcessor variant into single class. Now accepts optional expressionProcessor for recursive expression handling.

apply

public List<IRInstr> apply(ExprProcessingDetails details)

Specified by:

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

processOperandExpression

List<IRInstr> processOperandExpression(EK9Parser.ExpressionContext operandExpr,
 VariableDetails operandDetails)

Process operand expression using exprGenerator from generators struct. This allows handling complex nested expressions like -(-x) or -(a + b).
