public interface StreamStorable

Streaming interface for a data value. The format of the stream is data type dependent and represents the on-disk format of the value. That is it is different to the value an application will see through JDBC with methods like getBinaryStream and getAsciiStream.
If the value is NULL (DataValueDescriptor.isNull returns true then these methods should not be used to get the value.
