示例1: tryAdd
/// Tries to add another sequence onto the start or end of this one.
/// If it succeeds, the other sequence may also be modified and
/// should be considered "spent".
bool tryAdd(CoordinateSequence &other) {
//add the sequence at the end
if (last()==other.first()) {
coordinates.pop_back();
addToEnd(other.coordinates);
return true;
}
//add the sequence backwards at the end
if (last()==other.last()) {
coordinates.pop_back();
other.reverse();
addToEnd(other.coordinates);
return true;
}
//add the sequence at the beginning
if (first()==other.last()) {
coordinates.pop_front();
addToBegin(other.coordinates);
return true;
}
//add the sequence backwards at the beginning
if (first()==other.first()) {
coordinates.pop_front();
other.reverse();
