Class Scenario2AggregateWrapperGenerator

java.lang.Object

org.ek9lang.compiler.phase7.Scenario2AggregateWrapperGenerator

final class Scenario2AggregateWrapperGenerator
extends Object

Generates IR for Scenario 2 aggregate wrapper constructors, delegation, and function-accepting methods.

Handles:

• Constructor operations - create delegate instance and store in field
• Wrapping constructor - accepts existing delegate for return-type wrapping
• Standard delegation - load delegate, call method, handle return type wrapping/casting
• Function-accepting methods - inline implementations for whenPresent/whenOk/whenError

Method Details

isCallbackInvocationMethod

boolean isCallbackInvocationMethod(MethodSymbol method,
 Scenario2WrapperHelper helper)

Detect callback-invocation methods: methods whose contract is "invoke the supplied function on the contained value".

Structural signature: at least one parameter is a parameterised function type (Acceptor/Consumer/Predicate/...) and the method's return type is void. The void return is the discriminator that separates callback methods (Optional.whenPresent, Result.whenOk, Result.whenError — all void) from configuration methods that take a function as state (PriorityQueue.withComparator returns a new PriorityQueue and must go through standard delegation).

generateConstructorOperation

void generateConstructorOperation(IRConstruct construct,
 MethodSymbol method,
 String baseTypeName)

Generate constructor that creates the delegate instance.

generateWrappingConstructor

void generateWrappingConstructor(IRConstruct construct,
 AggregateSymbol aggregateSymbol,
 String baseTypeName)

Generate wrapping constructor that takes the base type as parameter.

generateDelegationOperation

void generateDelegationOperation(IRConstruct construct,
 MethodSymbol method,
 String baseTypeName)

Generate a delegation operation for a single method.

generateFunctionAcceptingMethod

void generateFunctionAcceptingMethod(IRConstruct construct,
 MethodSymbol method,
 String baseTypeName)

Generate inline implementation for methods that accept function wrapper types.
