Class ExportManager
java.lang.Object | +--edu.utah.janosvm.sys.ExportManager
- public final class ExportManager
- extends java.lang.Object
Tracks the importables associated with a single exportable. Each ExportManager is associated with exactly one Exportable. An exportable may have multiple ExportManagers (if it is exported under mutliple names, for example).
An ExportManager tracks the links between an exported object and its imports. This is required so that we can revoke any references when a team dies or the export is no longer available to other teams.
