All Implemented Interfaces:

java.lang.module.ModuleFinder

public class LayerModuleFinder
extends Object
implements java.lang.module.ModuleFinder

ModuleFinder implementation used by the module installed by LayerFactory to locate class definitions when an attempt is made to load a class into the module. The finder uses a ModuelReader which passes the request back to the installer of the module, allowing it either to generate or load the class definition as it sees fit.
