// std::vector
|

//
|

// The aim of all that follows would be to integrate std::vector with
|
||||
// Ruby as much as possible, namely, to allow the user to pass and
|
||||
// be returned Ruby arrays
|
||||
// const declarations are used to guess the intent of the function being
|
||||
// exported; therefore, the following rationale is applied:
|
||||
//
|
||||
// -- f(std::vector<T>), f(const std::vector<T>&), f(const std::vector<T>*):
|
||||
// the parameter being read-only, either a Ruby array or a
|
||||
// previously wrapped std::vector<T> can be passed.
|
||||
// -- f(std::vector<T>&), f(std::vector<T>*):
|
||||
// the parameter must be modified; therefore, only a wrapped std::vector
|
||||
// can be passed.
|
||||
// -- std::vector<T> f():
|
||||
// the vector is returned by copy; therefore, a Ruby array of T:s
|
||||
// is returned which is most easily used in other Ruby functions
|
||||
// -- std::vector<T>& f(), std::vector<T>* f(), const std::vector<T>& f(),
|
||||
// const std::vector<T>* f():
|
||||
// the vector is returned by reference; therefore, a wrapped std::vector
|
||||
// is returned
