// any of "advanced" C++ features (i.e. templates, exceptions, namespaces...)

|
// thus you should be able to compile it with practicaly any C++ compiler.

|
// same memory as long as neither of them is changed.
|

//

// std::string class, but adds some additional functions and should be at

|
// least as efficient than the standard implementation.
|

|
|
// String&" arguments than "const char *" if you assign the argument to

// another string.

|
// class to optimize string storage. Normally, we would store pointers to
|
|
// string, but as wxString is, in fact, itself a pointer (sizeof(wxString) is
|
|
// sizeof(char *)) we store these pointers instead. The cast to "wxString *" is
|

// really all we need to turn such pointer into a string!

//
|

// Of course, it can be called a dirty hack, but we use twice less memory and

|
// this approach is also more speed efficient, so it's probably worth it.
|

//
|

// Usage notes: when a string is added/inserted, a new copy of it is created,

// so the original string may be safely deleted. When a string is retrieved
