getType

public static CDOType getType(EStructuralFeature feature)
Since:
2.0

getType

public static CDOType getType(byte typeID)
Since:
4.0

getType

public static CDOType getType(EClassifier classifier)
Since:
2.0

getCoreType

public static CDOType getCoreType(EClassifier eDataType)
Core types includes also complex data like EAnnotation, and EEnum

Since:
2.0

getPrimitiveType

public static CDOType getPrimitiveType(Class<? extends Object> primitiveType)
Since:
2.0

getTypeOfObject

public static CDOType getTypeOfObject(Object object)
Since:
4.0

getPackageInfo

public static CDOPackageInfo getPackageInfo(Object value,
                                            CDOPackageRegistry packageRegistry)
Since:
2.0

getClassInfo

public static CDOClassInfo getClassInfo(EClass eClass)
Returns additional CDO infos for an EClass.

This operation is somewhat expensive because it synchronizes on the EClass and iterates over all adapters. Whenever possible use CDORevision.getClassInfo() or InternalCDOObject.getClassInfo().

Since:
2.0

getAllPersistentFeatures

@Deprecated
public static EStructuralFeature[] getAllPersistentFeatures(EClass eClass)
Deprecated. As of 4.2 use CDOModelUtil.getClassInfo(eClass).getAllPersistentFeatures().

Returns all persistent features of an EClass.

This operation is somewhat expensive because it synchronizes on the EClass and iterates over all adapters.

Since:
2.0

Since:
2.0

createPackageInfo

public static CDOPackageInfo createPackageInfo()
Since:
2.0

                                EPackage ePackage,
                                boolean zipped,
                                EPackage.Registry packageRegistry)
                         throws IOException
Throws:
IOException
Since:
