```
public class RMData
extends RMObject
implements java.io.Serializable
```
This class is like a StringBuffer for bytes instead of chars. It implements StringBuffer styled append() methods, only everything is forced into ASCII bytes. It is also enhanced with additional binary writing capabilities, so that many core types can be written as binary.
