AIS_SignatureFilter Class Reference

Selects Interactive Objects through their signatures
and types. The signature provides an
additional characterization of an object's type, and
takes the form of an index. The filter questions each
Interactive Object in local context to determine
whether it has an non-null owner, and if so, whether
it has the desired signature. 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. 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 only used in an 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
Some signatures have already been used by standard
objects delivered in AIS. These include:

 AIS_SignatureFilter (const AIS_KindOfInteractive aGivenKind, const Standard_Integer aGivenSignature)
 Initializes the signature filter, adding the signature
specification, aGivenSignature, to that for type,
aGivenKind, in AIS_TypeFilter.

Standard_Boolean IsOk (const Handle< SelectMgr_EntityOwner > &anobj) const
 Returns False if the transient is not an AIS_InteractiveObject.
Returns False if the signature of InteractiveObject
is not the same as the stored one in the filter...
