1 : : //- Class: CADeferredAttrib
2 : : //- Owner: Tim Tautges
3 : : //- Description: Cubit attribute for storing attributes that will be used later,
4 : : //- i.e. for entities which don't yet exist in the model
5 : : //- Checked by:
6 : : //- Version:
7 : : //-
8 : : //- Deferred attributes are used to store data on one solid model entity
9 : : //- which actually apply to a different entity, one which doesn't exist
10 : : //- in the solid model as stored (usually something like virtual geometry)
11 : : //-
12 : : //- This attribute saves/updates something like this:
13 : : //- 1) Normal attribute (mesh interval, scheme, etc.) updates
14 : : //- 2) Normal attribute writes:
15 : : //- - creates simple attribute, csa_ptr, and passes to
16 : : //- GeometryEntity::append_simple_attrib
17 : : //- - For virtual entities, this is implemented in
18 : : //- VirtualEntity::append_simple_attrib_virt
19 : : //- 3) Inside VE::append_simple_attrib_virt, the simple attribute is combined
20 : : //- with a uid for the owning ref entity and the two are used to make a
21 : : //- new *simple* deferred attribute
22 : : //- 4) The simple deferred attribute is put onto the first underlying entity
23 : : //- using TopologyBridge::append_simple_attrib
24 : : //-
25 : : //- To restore:
26 : : //- 1) Take dcsa, create CADeferredAttrib from it, and put it on owning entity:
27 : : //- - CADA stores uid from dcsa
28 : : //- - Then the dcsa is converted to a csa (CADA stuff removed) and stored
29 : : //- in CADA on owning entity
30 : : //- 2) When virtual geometry is created from actuating an attribute, CADA is notified;
31 : : //- CADA goes through the list of CADA's, looking for any that apply to the
32 : : //- new entity (based on uid)
33 : : //- 3) If any CADA's are found for the new entity, their csa data are converted to
34 : : //- a real CA, and that CA is put on the unactuatedCAs list in CADA.
35 : : //- 4) At the end of CubitAttribUser::auto_actuate_cubit_attrib, CADA::cleanup_cadas
36 : : //- is called, which keeps going through the unactuatedCAs list until nothing
37 : : //- new happens (no new unactuated cas)
38 : : //-
