• getContainerFeatureID

  public int getContainerFeatureID()

  Description copied from interface: CDORevisionData

  Returns the container feature ID. If the container isn't a navigable feature, this will be a negative ID indicating the inverse of the containment feature's ID.

  Provides the input to the calculation of the feature in the container revision that actually holds this revision.

  Usage Example:

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

  Returns:

  the container feature ID.

• getOrCreateList

  public CDOList getOrCreateList(EStructuralFeature feature)

  Description copied from interface: InternalCDORevision

  Same as getOrCreateList(feature, 0).

  Warning: Must be used with caution because list creation for an unsettable feature implies a transition from UNSET to SET!

• getOrCreateList

  public CDOList getOrCreateList(EStructuralFeature feature, int size)

  Description copied from interface: InternalCDORevision

  Returns the list that represents the passed feature, possibly creates it if needed.

  Warning: Must be used with caution because list creation for an unsettable feature implies a transition from UNSET to SET!

  Parameters:

  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 return null in this case.

  See Also:

  • InternalCDORevision.DO_NOT_CREATE_LIST

• constructList

  public CDOList constructList(EStructuralFeature feature, int size)

  Description copied from interface: InternalCDORevision

  Constructs a new many-valued feature list for revision loading. Unlike InternalCDORevision.getOrCreateList(EStructuralFeature, int), this operation never reuses an existing value and creates the requested logical size with internal construction slots.

• constructList

  public CDOList constructList(EStructuralFeature feature, int size, int initialChunk)

  Description copied from interface: InternalCDORevision

  Constructs a list for a DB read with the given initial chunk size.

  Parameters:

  feature - the many-valued feature

  size - the logical list size

  initialChunk - the number of values requested by the read, or CDORevision.UNCHUNKED for a full read

  Returns:

  the newly constructed list

• setList

  Since:

• bypassPermissionChecks

  public boolean bypassPermissionChecks(boolean on)

  Description copied from interface: InternalCDORevision

  Enables 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:

  4.3

• setListPreserving

  public void setListPreserving()

  Description copied from interface: InternalCDORevision

  The default behavior of a revision for calls to the InternalCDORevision.clear(EStructuralFeature) and InternalCDORevision.unset(EStructuralFeature) methods is to set the feature's value to null (discarding the value itself, a List). By calling this InternalCDORevision.setListPreserving() method the default behavior is changed; instead of setting the feature's value to null, the List.clear() method is called on the feature's list instance.
