Method Details

• sizeUnsynced

  int sizeUnsynced(InternalEObject eObject, EStructuralFeature feature)

  Returns the number of values in a many-valued feature without acquiring the view lock.

  The calling thread must already hold the owning view's access lock for the complete operation that uses this result. This method exists for composite list operations that keep that lock while performing their own index validation and subsequent store operation. Call InternalEObject.EStore.size(InternalEObject, EStructuralFeature) when no such outer lock is held.

  Parameters:

  eObject - the object that owns the feature.

  feature - the many-valued feature whose size is requested.

  Returns:

  the current number of values in the feature.

  Since:

  4.31

• moveUnsynced

  Object moveUnsynced(InternalEObject eObject, EStructuralFeature feature, int target, int source)

  Moves a value in a many-valued feature without acquiring the view lock.

  The calling thread must already hold the owning view's access lock for the complete operation. This method performs the same backing-store update and returns the same former value as InternalEObject.EStore.move(InternalEObject, EStructuralFeature, int, int). Call the synchronized method when no such outer lock is held.

  Parameters:

  eObject - the object that owns the feature.

  feature - the many-valued feature to update.

  target - the index to which the value is moved.

  source - the index from which the value is moved.

  Returns:

  the value formerly at source.

• removeUnsynced

  Object removeUnsynced(InternalEObject eObject, EStructuralFeature feature, int index)

  Removes a value from a many-valued feature using the same backing-store operation as InternalEObject.EStore.remove(InternalEObject, EStructuralFeature, int), without acquiring the owning view's access lock.

  The calling thread must already hold that lock for the complete operation. Call the synchronized method when no such outer lock is held.

  Parameters:

  eObject - the object that owns the feature.

  feature - the many-valued feature to update.

  index - the index of the value to remove.

  Returns:

  the removed value.

  4.31

  • InternalEObject.EStore.remove(InternalEObject, EStructuralFeature, int)

• addUnsynced

  void addUnsynced(InternalEObject eObject, EStructuralFeature feature, int index, Object value)

  Adds a value to a many-valued feature using the same backing-store operation as InternalEObject.EStore.add(InternalEObject, EStructuralFeature, int, Object), without acquiring the owning view's access lock.

  The calling thread must already hold that lock for the complete operation. The synchronized add(...) method remains the independently safe EStore entry point and must be used when no such outer lock is held.

  Parameters:

  eObject - the object that owns the feature.

  feature - the many-valued feature to update.

  index - the index at which the value is added.

  value - the value to add.

• getContainerFeatureID

  int getContainerFeatureID(InternalEObject eObject)

  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.

  Returns:

  the container feature ID.
