Package org.jboss.modules

Class FileSystemClassPathModuleFinder

java.lang.Object

org.jboss.modules.FileSystemClassPathModuleFinder

All Implemented Interfaces:

ModuleFinder

public class FileSystemClassPathModuleFinder
extends java.lang.Object
implements ModuleFinder

A module finder which loads modules from individual JARs or directories on the file system, supporting the JAR specification headers as well as the extended MANIFEST headers supported by JBoss Modules. The JAR files or modules may in turn contain nested module repositories inside of their modules subdirectories. Modules in nested repositories are only visible to the module that contains them.

Constructor Detail

FileSystemClassPathModuleFinder

public FileSystemClassPathModuleFinder(ModuleLoader baseModuleLoader)

Construct a new instance.

Parameters:

baseModuleLoader - the module loader to use to load module dependencies from (must not be null)

FileSystemClassPathModuleFinder

public FileSystemClassPathModuleFinder(ModuleLoader baseModuleLoader,
                                       java.util.function.Supplier<ModuleLoader> extensionModuleLoaderSupplier)

Construct a new instance.

Parameters:

baseModuleLoader - the module loader to use to load module dependencies from (must not be null)

extensionModuleLoaderSupplier - a supplier which yields a module loader for loading extensions (must not be null)

public FileSystemClassPathModuleFinder(java.util.function.Supplier<ModuleLoader> baseModuleLoaderSupplier,
                                       java.util.function.Supplier<ModuleLoader> extensionModuleLoaderSupplier)

Construct a new instance.

Parameters:

baseModuleLoaderSupplier - the supplier to supply a module loader for loading dependencies (must not be null)

extensionModuleLoaderSupplier - a supplier which yields a module loader for loading extensions (must not be null)

Method Detail

findModule

public ModuleSpec findModule(java.lang.String name,
                             ModuleLoader delegateLoader)
                      throws ModuleLoadException

Description copied from interface: ModuleFinder

Find a module specification for the given name. The default implementation delegates to the legacy ModuleFinder.findModule(ModuleIdentifier, ModuleLoader) method for now, however this behavior will be discontinued in the future.

Specified by:

findModule in interface ModuleFinder

Parameters:

name - the module name

delegateLoader - the module loader from which dependencies should be resolved

Returns:

the module specification, or null if no specification is found for this identifier

Throws:

ModuleLoadException
