//! Template CLI class providing the way to encapsulate instance of C++
|
|
//! class as a field in the C++/CLI (ref) class.
|
|
//!
|
|
//! It can be helpful to encapsulate OCCT Handles, maps, arrays, etc.
|
|
//!
|
|
//! Use of variable of the Haft type is very similar to that of encapsulated
|
|
//! class:
|
|
//! - Default constructor creates default-constructed C++ instance
|
|
//! - Non-default construction is possible by copy or by initialization from
|
|
//! compatible pointer (e.g. Haft for Handle can be initialized by pointer
|
|
//! returned by operator new for a handled class)
|
|
//! - Underlying C++ instance is accessed by operator ()
