public interface CDOPackageInfo extends org.eclipse.emf.common.notify.Adapter, org.eclipse.emf.ecore.EPackage.Descriptor, java.lang.Comparable<CDOPackageInfo>
Describes a singlepackageinstance of the nested package tree strucure represented by the containingpackage unit.While the containing package unit is in the
PROXYstate this package info acts as apackage descriptorin the associatedpackage registry. When that package unit is loaded all contained package infos/descriptors are resolved and replaced by their actual packages. At the same time the describing package info objects are attached as adapters to the resolved packages. This way the descriptive information is available before and after loading the packages.- Author:
