hasSystemModule

public static boolean hasSystemModule(String moduleName)

Checks if the Java run-time image contains a module with the given name.

getModuleResources

public static List<String> getModuleResources(Collection<Path> modulePath)

Gets all resources in the modules named by modules from the Java runtime image.

getSystemModuleResources

public static List<String> getSystemModuleResources(Collection<String> names)

openModuleByClass

public static void openModuleByClass(Class<?> declaringClass,
                                     Class<?> accessingClass)

Add the proper module opening to allow accesses from accessingClass to declaringClass.

exportAndOpenPackageToClass

public static void exportAndOpenPackageToClass(String moduleName,
                                               String packageName,
                                               boolean optional,
                                               Class<?> accessingClass)

Exports and opens a single package packageName in the module named moduleName to all unnamed modules.

exportAndOpenAllPackagesToUnnamed

public static void exportAndOpenAllPackagesToUnnamed(String name,
                                                     boolean optional)

Exports and opens all packages in the module named name to all unnamed modules.

Parameters:

optional - if false and there is no module named name, NoSuchElementException is thrown

exportAndOpenPackageToUnnamed

public static void exportAndOpenPackageToUnnamed(String name,
                                                 String pkg,

Exports and opens pkg in the module named name to all unnamed modules.

Parameters:

optional - if false and there is no module named name, NoSuchElementException is thrown

getModuleName

public static String getModuleName(Class<?> clazz)

Gets the name of the module containing clazz.

findResourcesInModules

public static void findResourcesInModules(Predicate<String> resourceNameFilter,
                                          BiConsumer<String,InputStream> operation)
                                   throws IOException

In the modules of the boot module layer, filters all resources that match the given predicate, and calls the operation on the matched resources. This is a temporary solution until we fully support modules in native-image

Parameters:

resourceNameFilter - predicate applied to all resource names in the module

operation - a function to process matched resources, it receives the name of the resources as the first argument and an open stream as the second argument

Throws:

IOException
