jdk.internal.module

pack-priv Interface SystemModules

Known Direct Implementers: jdk.internal.module.ExplodedSystemModules
Imports: java.lang.module.ModuleDescriptor, java.util.Map, .Set

A SystemModules object reconstitutes module descriptors and other modules attributes in an efficient way to avoid parsing module-info.class files at startup. Implementations of this class are generated by the "system modules" jlink plugin.
