Field Details

LAMBDA_FACTORY

private static final String LAMBDA_FACTORY

The name of a factory for a lambda expression.

See Also:

• Constant Field Values

FIELD_PREFIX

private static final String FIELD_PREFIX

A prefix for a field that represents a property of a lambda expression.

See Also:

• Constant Field Values

LAMBDA_TYPE_INFIX

private static final String LAMBDA_TYPE_INFIX

The infix to use for naming classes that represent lambda expression. The additional prefix is necessary because the subsequent counter is not sufficient to keep names unique compared to the original factory.

See Also:

• Constant Field Values

NOT_PREVIOUSLY_DEFINED

@AlwaysNull
private static final Class<?> NOT_PREVIOUSLY_DEFINED

A type-safe constant to express that a class is not already loaded when applying a class file transformer.

LAMBDA_NAME_COUNTER

private static final AtomicInteger LAMBDA_NAME_COUNTER

A counter for naming lambda expressions randomly.

byteBuddy

private final ByteBuddy byteBuddy

The Byte Buddy instance to use for creating lambda objects.

Constructor Details

LambdaInstanceFactory

protected LambdaInstanceFactory(ByteBuddy byteBuddy)

Creates a new lambda instance factory.

Parameters:

byteBuddy - The Byte Buddy instance to use for creating lambda objects.

Method Details

make

public byte[] make(Object targetTypeLookup,
 String lambdaMethodName,
 Object factoryMethodType,
 Object lambdaMethodType,
 Object targetMethodHandle,
 Object specializedLambdaMethodType,
 boolean serializable,
 List<Class<?>> markerInterfaces,
 List<?> additionalBridges,
 Collection<? extends ClassFileTransformer> classFileTransformers)

Applies this lambda meta factory.

Parameters:

targetTypeLookup - A lookup context representing the creating class of this lambda expression.

lambdaMethodName - The name of the lambda expression's represented method.

factoryMethodType - The type of the lambda expression's represented method.

lambdaMethodType - The type of the lambda expression's factory method.

targetMethodHandle - A handle representing the target of the lambda expression's method.

specializedLambdaMethodType - A specialization of the type of the lambda expression's represented method.

serializable - true if the lambda expression should be serializable.

markerInterfaces - A list of interfaces for the lambda expression to represent.

additionalBridges - A list of additional bridge methods to be implemented by the lambda expression.

classFileTransformers - A collection of class file transformers to apply when creating the class.

Returns:

A binary representation of the transformed class file.
