| 32 | //! filter questions each Interactive Object in local context |
| 33 | //! to determine whether it has an non-null owner, and if |
| 34 | //! so, whether it is of the desired type. If the object |
| 35 | //! returns true in each case, it is kept. If not, it is rejected. |
| 36 | //! By default, the interactive object has a None type |
| 37 | //! and a signature of 0. A filter for type specifies a |
| 38 | //! choice of type out of a range at any level enumerated |
| 39 | //! for type or kind. The choice could be for kind of |
| 40 | //! interactive object, of dimension, of unit, or type of axis, |
| 41 | //! plane or attribute. |
| 42 | //! If you want to give a particular type and signature to |
| 43 | //! your Interactive Object, you must redefine two virtual |
| 44 | //! methods: Type and Signature. |
| 45 | //! This filter is used in both Neutral Point and open local contexts. |
| 46 | //! In the Collector viewer, you can only locate |
| 47 | //! Interactive Objects which answer positively to the |
| 48 | //! positioned filters when a local context is open. |
