All Implemented Interfaces:

java.io.Serializable, ModuleScriptProvider

public class StrongCachingModuleScriptProvider
extends CachingModuleScriptProviderBase

A module script provider that uses a module source provider to load modules and caches the loaded modules. It strongly references the loaded modules, thus a module once loaded will not be eligible for garbage collection before the module provider itself becomes eligible.
