0020 //! Defines the type of evolution in old shape - new shape pairs.
0021 //! The definitions - in the form of the terms of
0022 //! the enumeration - are needed by the
0023 //! TNaming_NamedShape attribute and
0024 //! indicate what entities this attribute records as follows:
0025 //! -   PRIMITIVE
0026 //! -   New entities; in each pair, old shape is a
0027 //! null shape and new shape is a created
0028 //! entity.
0029 //! -   GENERATED
0030 //! -   Entities created from other entities; in
0031 //! each pair, old shape is the generator and
0032 //! new shape is the created entity.
0033 //! -   MODIFY
0034 //! -   Split or merged entities, in each pair, old
0035 //! shape is the entity before the operation
0036 //! and new shape is the new entity after the
0037 //! operation.
0038 //! -   DELETE
0039 //! -   Deletion of entities; in each pair, old
0040 //! shape is a deleted entity and new shape is null.
0041 //! -   SELECTED
0042 //! -   Named topological entities; in each pair,
0043 //! the new shape is a named entity and the
0044 //! old shape is not used.
0045 //!
0046 //! For a split which generates multiple faces, the
0047 //! attribute will contain many pairs with the same
0048 //! old shape; for a merge, it will contain many
0049 //! pairs with the same new shape.
0050 //! Finally, an example of delete would be a face
0051 //! removed by a Boolean operation.
