Class ManModuleReader

java.lang.Object

manifold.internal.runtime.ManModuleReader

public class ManModuleReader
extends Object

This class facilitates dynamic class loading via Type Manifolds in a Java 9 *modular* configuration. Note non-modular projects use Java 8, Java 9 with -source = 8, or Java 9 with no module-info.java; only a project using Java 9+ with module-info.java requires this class.

Basically ManModuleReader exploits Java 9's one-module-per-package rule... Since Java 9 maps each package name uniquely to a single module, a class of a given package must either load from that module or not load at all. ManModuleReader contributes to this loading by first delegating to the normal ModuleReader and, if the class fails to load, let Manifold attempt to load it.

Since Manifold is compiled exclusively with Java 8, this class implements ModuleReader structurally via proxy.
