Public Member Functions | |
| ezStreamReaderWithStats (ezStreamReader *pStream) | |
| virtual ezUInt64 | ReadBytes (void *pReadBuffer, ezUInt64 uiBytesToRead) override |
| Reads a raw number of bytes into the read buffer, this is the only method which has to be implemented to fully implement the interface. | |
| ezUInt64 | SkipBytes (ezUInt64 uiBytesToSkip) override |
| Helper method to skip a number of bytes (implementations of the stream reader may implement this more efficiently for example) | |

Implements ezStreamReader.

inlineoverridevirtual |
Helper method to skip a number of bytes (implementations of the stream reader may implement this more efficiently for example)
Reimplemented from ezStreamReader.
| ezUInt64 ezStreamReaderWithStats::m_uiBytesRead = 0 |
the number of bytes that were read from the wrapped stream public access so that users can read and modify this in case they want to reset the value at any time
