At the beginning of a run acquired in NSCLDAQ-11, A data format item is emitted specifying that the data format is that of NSCLDAQ-11. These items, in addition to a ring item header and an indicator that there is no body header, contain a major and minor version number.
In practice the minor version number is 0 and is not important for decoding ring items.
CDataFormatItem();
The constructor fills in the item with the major and minor vesions that define the data format.
const virtual uint16_t getMajor ();
Returns the major version of the data format. In practice, this is sufficient to establish the data format.
const virtual uint16_t getMinor();
Returns the minor version of the data format. In practice this is seldom necessary.
const virtual std::string typeName();
Return the string: Ring Item format version
const virtual std::string toString();
Returns a human readable string that describes the contents of the ring item.
const virtual void* getBodyHeader();
Returns nullptr since these items never have a body header.
virtual void setBodyHeader(uint64_t timestamp, uint32_t sourceId, uint32_t barrierType = 0);
No-op since these items don't have body headers.
