CDOPackageInfo (CDO Model Repository Documentation)

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.

- Method Detail
  - getPackageUnit
```
CDOPackageUnit getPackageUnit()
```
    Returns the package unit containing this package info.
  - getPackageURI
```
String getPackageURI()
```
    Returns the namespace URI of the package described by this package info.
  - getParentURI
```
String getParentURI()
```
    Returns the namespace URI of the super package of the package described by this package info.
  - getEPackage
```
EPackage getEPackage(boolean loadOnDemand)
```
    Returns the package described by this package info.
    
    Parameters:
    loadOnDemand - If true and the containing package unit is not LOADED the package unit is implicitely loaded. If false and this package unit is not LOADED null is returned.
  - isCorePackage
```
boolean isCorePackage()
```
    Returnes true if the package described by this package info is the Ecore model, false oterwise.
  - isResourcePackage
```
boolean isResourcePackage()
```
    Returnes true if the package described by this package info is the Eresource model, false oterwise.
  - isTypePackage
```
boolean isTypePackage()
```
    Returnes true if the package described by this package info is the Etypes model, false oterwise.
    
    Since:

  - isSystemPackage
```
boolean isSystemPackage()
```
    Returns true is this package info describes one of the models Ecore, Eresource or Etypes, false otherwise.
    Note that the models Ecore, Eresource and Etypes are expected to present as generated NATIVE models in all deployments.
