Method Detail

instantiate

public static InClasspathModuleRegistry instantiate(ClassLoader loader)
                                             throws IllegalStateException,
                                                    IOException

Instantiate an InClasspathModuleRegistry as the singleton ModuleRegistry

Parameters:

loader - the ClassLoader where to find the Modules

Returns:

the singleton instance

Throws:

IllegalStateException - thrown if there is already a singleton instance

IOException - reading files failed

instantiateOrGet

public static ModuleRegistry instantiateOrGet(ClassLoader loader)
                                       throws IllegalStateException,
                                              IOException

Obtain the already instantiated ModuleRegistry, or instantiate an InclasspathModuleRegistry as the singleton ModuleRegistry.

Parameters:

loader - the ClassLoader where to find the Modules

Returns:

the singleton instance

Throws:

IllegalStateException - thrown if there is already a singleton instance

IOException - reading files failed

createClassLoader

public ClassLoader createClassLoader(Module module,
                                     ClassLoader parentClassLoader)

ModuleRegistry also acts as a factory for the Modules' ClassLoaders. Here, all Modules share the same ClassLoaders.

Overrides:

createClassLoader in class AbstractModuleRegistry

Parameters:

module - the Module for which to create a ClassLoader

parentClassLoader - the ClassLoader to use as the parent ClassLoader

Returns:

the ClassLoader to use with the Module

findModuleMetas

protected static HashMap<String,MiniModuleMetaMap> findModuleMetas(ClassLoader cl)
                                                            throws IOException

Find the ModuleMetas available to this ClassLoader.

Parameters:

cl - the class loader

Returns:

the found ModuleMetas, keyed by module name, and ordered by version

Throws:

IOException - reading files failed
