AIS_TypeFilter Class Reference

Selects Interactive Objects through their types. The
filter questions each Interactive Object in local context
to determine whether it has an non-null owner, and if
so, whether it is of the desired type. If the object
returns true in each case, it is kept. If not, it is rejected.
By default, the interactive object has a None type
and a signature of 0. A filter for type specifies a
choice of type out of a range at any level enumerated
for type or kind. The choice could be for kind of
interactive object, of dimension, of unit, or type of axis,
plane or attribute.
If you want to give a particular type and signature to
your Interactive Object, you must redefine two virtual
methods: Type and Signature.
This filter is used in both Neutral Point and open local contexts.
In the Collector viewer, you can only locate
Interactive Objects which answer positively to the
positioned filters when a local context is open.
Warning
When you close a local context, all temporary
interactive objects are deleted, all selection modes
concerning the context are cancelled, and all content
filters are emptied.
