All Superinterfaces:: Adapter, CDOClassInfo

public interface InternalCDOClassInfo extends CDOClassInfo

Cached model metadata used by revisions and CDO objects to map EMF features to their stored slots. It defines which features are persisted, how transient object settings are laid out, and how model-specific persistence filters transform values before storage.

Method

Description

InternalCDOClassInfo.PersistenceFilter

getPersistenceFilter(EStructuralFeature feature)

Obtains a rule that filters/transforms the persist values of the given feature.

int

getPersistentFeatureIndex(int featureID)

Returns the index of the specified feature in the CDORevisionImpl.values array, never NO_SLOT.

int

getPersistentFeatureIndex(EStructuralFeature feature)

Returns the index of the specified feature in the CDORevisionImpl.values array, never NO_SLOT.

InternalCDORevision

getRevisionForID(CDOID id)

int

getSettingsFeatureCount()

Returns the number of features whose values are always stored in the CDOObjectImpl.eSettings array, whether an object is in CDOState.TRANSIENT or not.

int

getSettingsFeatureIndex(int featureID)

Returns the index of the specified feature in the CDOObjectImpl.eSettings array, or NO_SLOT if the feature is non-transient or single-valued.

int

getTransientFeatureCount()

Returns the number of features whose values are additionally stored in the CDOObjectImpl.eSettings array, if an object is in CDOState.TRANSIENT.

int

getTransientFeatureIndex(int featureID)

Returns the index of the specified feature in the CDOObjectImpl.eSettings array, or NO_SLOT if the feature is transient or many-valued

int

getTransientFeatureIndex(EStructuralFeature feature)

  Parameters:
  
  feature - a feature to be persisted
  
  Returns:
  
  a persistence filter rule for the feature, or null if it has no filter but just follows the default persistence rules
