An adaptation of std::stringstream?

Hi,

So I have been wondering why there is no Unreal-version of these two standard library classes:

  • std::stringstream
  • std::wstringstream

I think it could be useful, and I have personally found the need for them several times now. The biggest argument I think is that I have to use TCHAR_TO_WCHAR() and WCHAR_TO_TCHAR() macros to safely convert to/from a format so I can use std::wstringstream (given that I’m actually doing things the right way!).

A much more straight-forward and safer approach would be to have:

template <typename CharType> class TStringStream;

using FStringStream = TStringStream<TCHAR>;

[...]
FStringStream ss;
ss << TEXT("Please append me");

[...]
FString  str = TEXT("A text consisting of several words together forming a sentence.");
FStringStream ss(str);
FString word;
ss >> word;
while (!word.empty)
{
    print(word); // default usage of each word
    ss >> word;
}

So this is kind of both a question and a request. Can we have this? And why does it not already exist?

Thanks!
