#include <QBuffer.h>
Inheritance diagram for FX::QBuffer:
There's little more to say than that this class works with a QByteArray to provide an i/o device working directly with memory. It auto-extends the array if needed etc. It's also thread-safe so multiple threads can use the i/o device at once.
Note that QBuffer ignores CR/LF translation (IO_Translate). Anything dealing with files in TnFOX does though, so the conversion can be done then.
Since there is no reference counted sharing in TnFOX, buffer() and setBuffer() return and take references.
