| 4 | // CompoundParticle |
| 5 | // |
| 6 | // A compound particle class that holds other (daughter) particles. The class provides |
| 7 | // the same features as the CompositeParticle but allows to transfer ownership of daughters. |
| 8 | // This class is not supposed and can not be stored in a tree. |
