Imports
java.lang.module.Configuration, .ResolvedModule, java.util.HashMap, .Map, .Set, java.util.function.Function, jdk.internal.loader.ClassLoaders
Supports the mapping of modules to class loaders. The set of modules mapped to the boot and platform class loaders is generated at build time from this source file.

Nested and Inner Type Summary

Modifier and TypeClass and Description
private static class
ModuleLoaderMap.Mapper

Maps the system modules to the built-in class loaders.

private static class
ModuleLoaderMap.Modules

Constructor Summary

AccessConstructor and Description

ModuleLoaderMap()

Method Summary

Modifier and TypeMethod and Description
public static Set<String>
bootModules()

Returns the names of the modules defined to the boot loader.

public static boolean
isBuiltinMapper(Function<String, ClassLoader> clf)

When defining modules for a configuration, we only allow defining modules to the boot or platform classloader if the ClassLoader mapping function originate from here.

pack-priv static Function<String, ClassLoader>
mappingFunction(Configuration cf)

Returns a function to map modules in the given configuration to the built-in class loaders.

public static Set<String>
nativeAccessModules()

Returns the names of the modules defined to the application loader which perform native access.

public static Set<String>
platformModules()

Returns the names of the modules defined to the platform loader.
