Public functions

void Dispose() pure virtual

Closes the stream and releases all assigned resources.

auto Seek(std::int64_t offset, SeekOrigin origin) -> std::int64_t pure virtual

Seeks in an opened stream.

auto GetPosition() const -> std::int64_t pure virtual

Tells the seek position of an opened stream.

auto Read(void* destination, std::int64_t bytesToRead) -> std::int64_t pure virtual

Reads a certain amount of bytes from the stream to a buffer.

auto Write(const void* source, std::int64_t bytesToWrite) -> std::int64_t pure virtual

Writes a certain amount of bytes from a buffer to the stream.

auto Flush() -> bool pure virtual

Clears all buffers for this stream and causes any buffered data to be written to the underlying device.

auto IsValid() -> bool pure virtual

Returns true if the stream has been sucessfully opened.

auto GetSize() const -> std::int64_t pure virtual

Returns stream size in bytes.

auto CopyTo(Stream& targetStream) -> std::int64_t

Reads the bytes from the current stream and writes them to the target stream.

template<typename T, class = typename std::enable_if<std::is_trivially_constructible<T>::value>::type>

auto ReadValue() -> T

Reads a trivial value from the stream.

template<typename T, class = typename std::enable_if<std::is_trivially_constructible<T>::value>::type>

void WriteValue(const T& value)
