```
public class RawPacket
extends Object
implements org.jitsi.utils.ByteArrayBuffer
```
When using TransformConnector, a RTP/RTCP packet is represented using RawPacket. RawPacket stores the buffer holding the RTP/RTCP packet, as well as the inner offset and length of RTP/RTCP packet data. After transformation, data is also store in RawPacket objects, either the original RawPacket (in place transformation), or a newly created RawPacket. Besides packet info storage, RawPacket also provides some other operations such as readInt() to ease the development process. FIXME This class needs to be split/merged into RTPHeader, RTCPHeader, ByteBufferUtils, etc.

    id - the ID with which to add the extension.
