| 7 | // This is a simple container to put objects in. It defines all functions |
| 8 | // which are necessary to describe an object which can be filled with |
| 9 | // other things. |
| 10 | // |
| 11 | // It will support restrictions for volume, weight etc. |
| 12 | // |
| 13 | // The following properties are defined: |
| 14 | // P_MAX_WEIGHT - maximum weight which container can carry |
| 15 | // P_WEIGHT_CONTENTS - current contents |
| 16 | // P_WEIGHT - builtin property: read->total weight, write->own weight |
| 17 | // |
| 18 | // Functions for manipulation of weight |
| 19 | // MayAddWeight(weight) - Can <weight> be inserted? |
| 20 | // AddWeight(weight) - Add an amount of <weight> |
| 21 | // |
| 22 | // IMPORTANT: unit should be interpreted as grams (g). |
