Method Detail

find

public Module find(Class clazz)

Description copied from interface: ModulesRegistry

Finds the Module that owns the given class.

Specified by:

find in interface ModulesRegistry

null if the class is loaded outside the module system.

getModules

public Collection<Module> getModules(String moduleName)

Description copied from interface: ModulesRegistry

Returns the list of shared Modules registered in this instance whose name matches the given name

The returned list will not include the modules defined in the ancestor ModulesRegistrys.

Specified by:

getModules in interface ModulesRegistry

an umodifiable list of loaded modules having names that match the given name

getModules

public Collection<Module> getModules()

Description copied from class: AbstractModulesRegistryImpl

The returned list will not include the modules defined in the ancestor AbstractModulesRegistryImpls.

Specified by:

getModules in interface ModulesRegistry

Overrides:

getModules in class AbstractModulesRegistryImpl

Returns:

an umodifiable list of loaded modules

makeModuleFor

public Module makeModuleFor(String name,
                   String version,
