com.reportmill.base.RMData
All Implemented Interfaces:
RMArchiver.Archiving, Serializable, Cloneable
Direct Known Subclasses:
RMFlashBuffer
public class RMData extends RMObject implements 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.
