Class Description

BrRootCalibrationsDb(const Char_t* name, const Char_t* title)

 Normal constructor. Singleton.

Bool_t Connect(Option_t* option)

 Overloaded here, so that we can get pointers to the tables.

BrCalibrationsDb* Instance(void)

 Returns an instance of the Calibration Database connection.
 Connection _must_ be constructed somewhere previous to calling
 this static method.

void AddRevision(BrDbRevision* revision)

 Add a Revision to the database. Warns if there exist overlapping
 revsisions wiith the same type.

void AddRevisionType(BrDbRevisionType* type)

 Add a Revision Type to the database. Fails if it allready exists
 in the database (throws a BrExcpetion)

void AddParameter(BrDbParameter* param)

 Add a parameter to the database. Fails if it allready exists in
 the database (throws a BrExcpetion)

TObjArray* GetXParameter(const Char_t* condition)

 Returns (unconditionally) all parameters

TObjArray* GetXRevision(const Char_t* condition)

 Returns (unconditionally) all Revisions

TObjArray* GetXRevisionType(const Char_t* condition)

 Returns (unconditionally) all RevisionTypes

BrDbParameter* GetParameter(const Char_t* condition)

 Not implmented.

BrDbParameter* GetParameter(const Char_t* name, Int_t detectorId)

 Find a parameter with name <name> belonging to detector
 <detectorId>

BrDbRevision* GetRevision(const Char_t* condition)

 Not implmented.

BrDbRevision* GetRevision(Int_t parameterId, Int_t start, Int_t stop, Int_t typeId, Int_t parameterPolicy)

 Find a single Revision in the database belonging to Parameter
 parameterId, inside the time period from start (inclusive) to
 stop (exclusive), and having type typeId. stop may be negative,
 in which case the database is serached for time preiod containg
 start. typeId, may be less then or equal to -1, in which case
 only standard Revision Types are searched.  If typeId is zero,
 any revision will be searched. Default is to only search standard
 revisions.

void RevisionSort(TObjArray& a, Bool_t asc, Int_t which)

 PRIVATE METHOD
 Sort a TObjArray containing BrDbRevision objects, and return it
 in itself.
 Parameters:
   a                The array
   asc      kTRUE   Sort ascending
            kFLASE  Sort descending
   which    0       Sort by date
            1       Sort by validStart
            2       Sort by validEnd
 The algorithm used is straight insertion

BrDbRevisionType* GetRevisionType(const Char_t* condition)

 Not implmented.

GetRevisionType(const Char_t* name, const Char_t* inComment)

 Query the database for a single Revision Type. The first argument
 is the name of the revision (mandetory), and the second is a
 string to search for in the comment field. The second arguement
 may by "", NULL, or 0, in which case no query is perfomed on the
 comment field. If a second argument is specified, the first
 argument is a substring to search for.
