DEFINE_STANDARD_HANDLE(ShapeAnalysis_Wire, Standard_Transient)

//! This class provides analysis of a wire to be compliant to
//! CAS.CADE requirements.
//!
//! The functionalities provided are the following:
//! 1. consistency of 2d and 3d edge curve senses
//! 2. connection of adjacent edges regarding to:
//! a. their vertices
//! b. their pcurves
//! c. their 3d curves
//! 3. adjacency of the edge vertices to its pcurve and 3d curve
//! 4. if a wire is closed or not (considering its 3d and 2d
//! contour)
//! 5. if a wire is outer on its face (considering pcurves)
//!
//! This class can be used in conjunction with class
//! ShapeFix_Wire, which will fix the problems detected by this class.
//!
//! The methods of the given class match to ones of the class
//! ShapeFix_Wire, e.g., CheckSmall and FixSmall.
//! This class also includes some auxilary methods
//! (e.g., CheckOuterBound, etc.),
//! which have no pair in ShapeFix_Wire.
//!
//! Like methods of ShapeFix_Wire the ones of this class are
//! grouped into two levels:
//! - Public which are recommended for use (the most global
//! method is Perform),
//! - Advanced, for optional use only
//!
//! For analyzing result of Public API checking methods use
//! corresponding Status... method.
//! The 'advanced' functions share the single status field which
//! contains the result of the last performed 'advanced' method.
//! It is quried by the method LastCheckStatus().
//!
//! In order to prepare an analyzer, it is necessary to load a wire,
//! set face and precision.
