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

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,
