// const declarations are used to guess the intent of the function being

|
//
|
||
|
// -- f(std::queue<T>), f(const std::queue<T>&):
|
||
|
// the parameter being read-only, either a sequence or a
|
||
|
// previously wrapped std::queue<T> can be passed.
|
||
|
// -- f(std::queue<T>&), f(std::queue<T>*):
|
||
|
// the parameter may be modified; therefore, only a wrapped std::queue
|
||
|
// can be passed.
|
||
|
// -- std::queue<T> f(), const std::queue<T>& f():
|
||
|
// the queue is returned by copy; therefore, a sequence of T:s
|
||
|
// is returned which is most easily used in other functions
|
||
|
// -- std::queue<T>& f(), std::queue<T>* f():
|
||
|
// the queue is returned by reference; therefore, a wrapped std::queue
|
||
|
// is returned
|
||
|
// -- const std::queue<T>* f(), f(const std::queue<T>*):
|
||
|
// for consistency, they expect and return a plain queue pointer.
