Interface DSNoData

All Superinterfaces:
DSPacket, DSSerializable
@Deprecated public interface DSNoData extends DSPacket
Deprecated.
replaced by SubjectErrorEvent

This class can be used to send a 'NoData' message to a DataSource peer that signals that an object has not been found and the reason why. This is most likely to occur when an active DataSource need to indicate, having received a request, that data is not available.

Should a request come in for which there is no data then a NoData message should be sent. The flags ( F_NOTFOUND, F_READDENY, F_WRITEDENY, F_DELETEOBJECT, F_UNAVAILABLE ) that may be sent are mutually exclusive.
