Examples of DataRecord

org.apache.jackrabbit.core.data.DataRecord
Immutable data record that consists of a binary stream.
org.fieldapi.DataRecord
This is the representation for any data measured or handled by the system. The data record contains :
- a timestamp refering a date and time relative to UTC.
- an indication of the quality of the record.
- the value itself.
Note that the timestamp is ALWAYS the moment the DataRecord was created, so basically the idea is if a sensor measures something, in the best case the value is directly completed with a timestamp and this timestamp does not change anymore. For OutputChannels this means that the timestamp is not the point in time when the output has to be changed, it is rather the moment in time the system has decided to change the output. Clearly the output has to react as soon as possible to this change. @author Dominique Gabioud, Patrice Rudaz, Michael Clausen
