getSettingsFeatureIndex

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.

See Also:

getSettingsFeatureCount()

getTransientFeatureCount

int getTransientFeatureCount()

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

These are the non-transient and/or single-valued features.

getPersistenceFilter

InternalCDOClassInfo.PersistenceFilter getPersistenceFilter(EStructuralFeature feature)

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