// std::vector |

|
// The aim of all that follows would be to integrate std::vector with |
|
// Tcl as much as possible, namely, to allow the user to pass and |
|
// be returned Tcl lists. |
|
// 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 Tcl list 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 Tcl list of T:s |
|
// is returned which is most easily used in other Tcl functions procs |
|
// -- 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 |
