Adaptations for compiling with GCC 4.7 and 4.8: - Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7. - Missing includes added. - Fixed bugs related to misuse of direct casts of handle. - Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions

//! The GeomAPI package provides an Application
|
|
//! Programming Interface for the Geometry.
|
|
//!
|
|
//! The API is a set of classes and methods aiming to
|
|
//! provide :
|
|
//!
|
|
//! * High level and simple calls for the most common
|
|
//! operations.
|
|
//!
|
|
//! * Keeping an access on the low-level
|
|
//! implementation of high-level calls.
|
|
//!
|
|
//! The API provides classes to call the algorithmes
|
|
//! of the Geometry
|
|
//!
|
|
//! * The constructors of the classes provides the
|
|
//! different constructions methods.
|
|
//!
|
|
//! * The class keeps as fields the different tools
|
|
//! used by the algorithmes
|
|
//!
|
|
//! * The class provides a casting method to get
|
|
//! automatically the result with a function-like
|
|
//! call.
|
|
//!
|
|
//! For example to evaluate the distance <D> between a
|
|
//! point <P> and a curve <C>, one can writes :
|
|
//!
|
|
//! D = GeomAPI_ProjectPointOnCurve(P,C);
|
|
//!
|
|
//! or
|
|
//!
|
|
//! GeomAPI_ProjectPointOnCurve PonC(P,C);
|
|
//! D = PonC.LowerDistance();
