Class ModuleLayerFromSingleClassLoaderDecorator

java.lang.Object

net.bytebuddy.dynamic.loading.ModuleLayerFromSingleClassLoaderDecorator

All Implemented Interfaces:

ClassLoaderDecorator

@Enhance
public class ModuleLayerFromSingleClassLoaderDecorator
extends Object
implements ClassLoaderDecorator

A simple implementation of a ClassLoaderDecorator that creates module layers for dynamically generated types using the Java Module System. The module information is resolved from a provided module-info class. Without such a class, the decoration is omitted.

Constructor Details

ModuleLayerFromSingleClassLoaderDecorator

protected ModuleLayerFromSingleClassLoaderDecorator(@MaybeNull
 ClassLoader classLoader,
 Object moduleLayer,
 String name,
 Set<String> packages)

Creates a new module layer from module info decorator.

Parameters:

classLoader - The class loader to delegate to when types are not handled by the module layer.

moduleLayer - The module layer containing the dynamically created module.

name - The name of the module within the module layer.

packages - The packages that are exported by the module.

Method Details

isSkipped

public boolean isSkipped(TypeDescription typeDescription)

Determines if a type should be skipped from class loader decoration.

Specified by:

isSkipped in interface ClassLoaderDecorator

Parameters:

typeDescription - The type description to check.

Returns:

true if the type should be skipped from decoration.

apply

@MaybeNull
public ClassLoader apply(TypeDescription typeDescription)

Applies this decorator to resolve a class loader for the given type.

Specified by:

apply in interface ClassLoaderDecorator

Parameters:

typeDescription - The type description for which to resolve a class loader.

Returns:

The class loader to use for the given type or null for the bootstrap class loader.
