66//! A topological attribute can be seen as a hook
67//! into the topological structure. To this hook,
68//! data can be attached and references defined.
69//! It is used for keeping and access to
70//! topological objects and their evolution. All
71//! topological objects are stored in the one
72//! user-protected TNaming_UsedShapes
73//! attribute at the root label of the data
74//! framework. This attribute contains map with all
75//! topological shapes, used in this document.
76//! To all other labels TNaming_NamedShape
77//! attribute can be added. This attribute contains
78//! references (hooks) to shapes from the
79//! TNaming_UsedShapes attribute and evolution
80//! of these shapes. TNaming_NamedShape
81//! attribute contains a set of pairs of hooks: old
82//! shape and new shape (see the figure below).
83//! It allows not only get the topological shapes by
84//! the labels, but also trace evolution of the
85//! shapes and correctly resolve dependent
86//! shapes by the changed one.
87//! If shape is just-created, then the old shape for
88//! accorded named shape is an empty shape. If
89//! a shape is deleted, then the new shape in this named shape is empty.
90//! Different algorithms may dispose sub-shapes
91//! of the result shape at the individual label depending on necessity:
92//! - If a sub-shape must have some extra attributes (material of
93//! each face or color of each edge). In this case a specific sub-shape is
94//! placed to the separate label (usually, sub-label of the result shape label)
95//! with all attributes of this sub-shape.
96//! - If topological naming is needed, a necessary and sufficient
97//! (for selected sub-shapes identification) set of sub-shapes is
98//! placed to the child labels of the result
99//! shape label. As usual, as far as basic solids and closed shells are
100//! concerned, all faces of the shape are disposed. Edges and vertices
101//! sub-shapes can be identified as intersection of contiguous faces.
102//! Modified/generated shapes may be placed to one named shape and
103//! identified as this named shape and source named shape that also can be
104//! identified with used algorithms.
105//! TNaming_NamedShape may contain a few
106//! pairs of hooks with the same evolution. In this
107//! case topology shape, which belongs to the
108//! named shape, is a compound of new shapes.
109//! The data model contains both the topology
110//! and the hooks, and functions handle both
111//! topological entities and hooks. Consider the
112//! case of a box function, which creates a solid
113//! with six faces and six hooks. Each hook is
114//! attached to a face. If you want, you can also
115//! have this function create hooks for edges and
116//! vertices as well as for faces. For the sake of
117//! simplicity though, let's limit the example.
118//! Not all functions can define explicit hooks for
119//! all topological entities they create, but all
120//! topological entities can be turned into hooks
121//! when necessary. This is where topological naming is necessary.
