      • getPersistentFeatureIndex

        int getPersistentFeatureIndex​(org.eclipse.emf.ecore.EStructuralFeature feature)
                       throws java.lang.IllegalArgumentException
        Returns the index of the specified feature in the CDORevisionImpl.values array, never NO_SLOT.
        Throws:
        java.lang.IllegalArgumentException - if the specified feature is not persistent.
        See Also:

      • getPersistentFeatureIndex

        int getPersistentFeatureIndex​(int featureID)
                       throws java.lang.IllegalArgumentException
        Returns the index of the specified feature in the CDORevisionImpl.values array, never NO_SLOT.
        Throws:
        java.lang.IllegalArgumentException - if the specified feature is not persistent.
        See Also:
        getPersistentFeatureIndex(EStructuralFeature)

      • getSettingsFeatureCount

        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.

        These are the transient and/or many-valued features.

        See Also:
        getSettingsFeatureIndex(int)

      • 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.

        See Also:
        getTransientFeatureIndex(int)

      • getTransientFeatureIndex

        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

      • getPersistenceFilter

        InternalCDOClassInfo.PersistenceFilter getPersistenceFilter​(org.eclipse.emf.ecore.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
