preloadModule

protected Module preloadModule(ModuleIdentifier identifier)
                        throws ModuleLoadException

Description copied from class: ModuleLoader

Preload a module based on an identifier. By default, no delegation is done and this method simply invokes ModuleLoader.loadModuleLocal(ModuleIdentifier). A delegating module loader may delegate to the appropriate module loader based on loader-specific criteria (via the ModuleLoader.preloadModule(ModuleIdentifier, ModuleLoader) method).

Overrides:

preloadModule in class ModuleLoader

Parameters:

identifier - the module identifier

Returns:

the load result, or null if the module is not found

Throws:

ModuleLoadException - if an error occurs

findModule

protected ModuleSpec findModule(ModuleIdentifier moduleIdentifier)
                         throws ModuleLoadException

Description copied from class: ModuleLoader

Find a Module's specification in this ModuleLoader by its identifier. This can be overriden by sub-classes to implement the Module loading strategy for this loader. The default implementation iterates the module finders provided during construction.

If no module is found in this module loader with the given identifier, then this method should return null. If the module is found but some problem occurred (for example, a transitive dependency failed to load) then this method should throw a ModuleLoadException of the relevant type.

Overrides:

findModule in class ModuleLoader

Parameters:

moduleIdentifier - the module identifier

Returns:

the module specification, or null if no module is found with the given identifier

Throws:

ModuleLoadException - if any problems occur finding the module

toString

public java.lang.String toString()

Description copied from class: ModuleLoader

Get the string representation of this module loader.

Overrides:

toString in class ModuleLoader

Returns:

the string representation

addClassPath

private void addClassPath(ModuleSpec.Builder builder,
                          java.lang.String classPath)
                   throws ModuleLoadException

Adds the class path entries as dependencies on the builder.

Parameters:

builder - the builder to add the dependency entries to.

classPath - the class path to process

Throws:

ModuleLoadException - if the class path entry is not found or the entry is a directory.
