Interface CDOPackageInfo

All Superinterfaces:
Adapter, Comparable<CDOPackageInfo>, EPackage.Descriptor
All Known Subinterfaces:
InternalCDOPackageInfo
public interface CDOPackageInfo extends Adapter, EPackage.Descriptor, Comparable<CDOPackageInfo>
Describes a single package instance of the nested package tree strucure represented by the containing package unit.

While the containing package unit is in the PROXY state this package info acts as a package descriptor in the associated package 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.
