CDORevision revision = ...; CDORevision container = Util.getRevision(revision.data().getContainerID()); int containingFeatureID = revision.data().getContainingFeatureID(); EStructuralFeature feature = containingFeatureID <= InternalEObject.EOPPOSITE_FEATURE_BASE ? container.getEClass().getEStructuralFeature(InternalEObject.EOPPOSITE_FEATURE_BASE - containingFeatureID) : ((EReference)revision.getEClass().getEStructuralFeature(containingFeatureID)).getEOpposite(); -

Description copied from interface:InternalCDORevisionSame asgetOrCreateList(feature, 0).Warning: Must be used with caution because list creation for an

getOrCreateList
Description copied from interface:InternalCDORevisionReturns the list that represents the passed feature, possibly creates it if needed.Warning: Must be used with caution because list creation for an
unsettablefeature implies a transition from UNSET to SET!size- the initialCapacity of a new list to be created if this revision has no list so far (its size will always be 0), or -1 to skip list creation and returnnullin this case.- See Also:

bypassPermissionChecks
public boolean bypassPermissionChecks(boolean on) Description copied from interface:InternalCDORevisionEnables or disables permission checking for this revision.This method is used on the client side if the framework changes the revision on another user's behalf, e.g., during invalidation or general revision copying. It's safe to offer this method on the client side because the server is always the permission checking authority (during load or commit).

isListPreserving
public boolean isListPreserving()- Since:

-
setListPreserving
public void setListPreserving()Description copied from interface:InternalCDORevisionThe default behavior of a revision for calls to theInternalCDORevision.clear(EStructuralFeature)andInternalCDORevision.unset(EStructuralFeature)methods is to set the feature's value to null (discarding the value itself, a List). By calling thisInternalCDORevision.setListPreserving()method the default behavior is changed; instead of setting the feature's value to null, theList.clear()method is called on the feature's list instance.- Since:
