Class StandaloneProjectMap.PackageDescriptor

java.lang.Object
  org.eclipse.ocl.examples.domain.utilities.StandaloneProjectMap.PackageDescriptor

All Implemented Interfaces:

StandaloneProjectMap.IPackageDescriptor

Enclosing class:

StandaloneProjectMap

public static final class StandaloneProjectMap.PackageDescriptor
extends java.lang.Object
implements StandaloneProjectMap.IPackageDescriptor

PackageDescriptor supports lazy class loading and initialization of a compiled Ecore package. Class loading occurs in the context of the ProjectMap, which performs classpath scans, so it is assumed that everything is visible. Re-use in a larger context may require a new ProjectMap to be created. If a PackageDescriptor is installed under multiple URIs, the resource created by the first load is shared by all subsequent resolutions. If a PackageDescriptor is set to useModel, the *.ecore file is loaded to provide the EPackage, rather than the Java className. A PackageDescriptor maintains the declared context of a package which may be shared by many ResourceSets. In contrast a PackageStatus maintains the actual state of a package for a particular EPackage.Registry, each of which may have a distinct ResourceLoadStrategy and consequently may not load the same EPackage.
