52 DEFINE_STANDARD_HANDLE(ShapeAnalysis_Wire, Standard_Transient)
53 
54 //! This class provides analysis of a wire to be compliant to
55 //! CAS.CADE requirements.
56 //!
57 //! The functionalities provided are the following:
58 //! 1. consistency of 2d and 3d edge curve senses
59 //! 2. connection of adjacent edges regarding to:
60 //! a. their vertices
61 //! b. their pcurves
62 //! c. their 3d curves
63 //! 3. adjacency of the edge vertices to its pcurve and 3d curve
64 //! 4. if a wire is closed or not (considering its 3d and 2d
65 //! contour)
66 //! 5. if a wire is outer on its face (considering pcurves)
67 //!
68 //! This class can be used in conjunction with class
69 //! ShapeFix_Wire, which will fix the problems detected by this class.
70 //!
71 //! The methods of the given class match to ones of the class
72 //! ShapeFix_Wire, e.g., CheckSmall and FixSmall.
73 //! This class also includes some auxiliary methods
74 //! (e.g., CheckOuterBound, etc.),
75 //! which have no pair in ShapeFix_Wire.
76 //!
77 //! Like methods of ShapeFix_Wire the ones of this class are
78 //! grouped into two levels:
79 //! - Public which are recommended for use (the most global
80 //! method is Perform),
81 //! - Advanced, for optional use only
82 //!
83 //! For analyzing result of Public API checking methods use
84 //! corresponding Status... method.
85 //! The 'advanced' functions share the single status field which
86 //! contains the result of the last performed 'advanced' method.
87 //! It is queried by the method LastCheckStatus().
88 //!
89 //! In order to prepare an analyzer, it is necessary to load a wire,
90 //! set face and precision.
