WrappedOutputStream Class Reference
WrappedOutputStream
class WrappedOutputStream : OutputStream, StreamDelegateThis class wraps an output stream.
This somehow helps handling output streams. Looks like one cannot direcly use a sub-classed output stream, so there is a stream kept as an internal variable. In addition there is a computed property to return this variable. That way it can be overwritten by sub classe. Maybe there is a better way to handle this.
