Class Description


 HOraSlowManager

 Manager class to access the slowcontrol data in Oracle
 (Singleton with global pointer gHOraSlowManager)

 It allows to read and draw the raw and summary data for a list of channels in a
 specified time range.

 See documentation and example macros in Wiki, topic OracleEpicsArchiveHydraInterface

HOraSlowManager()

 Default constructor

~HOraSlowManager()

 Destructor

Bool_t openOraInput()

 Connnects to Oracle (is done automatically when needed)

void closeOraInput()

 Closes the Oracle connection

HOraSlowPartition* setPartition(const char* pName, const char* t1,const char* t2)

 Sets the data partition and the time range t1 - t2 (typically smaller then the time range of the partition)
 Dates must be specified in the format yyyy-mm-dd hh:mi:ss.
 If no time range is specified, the data of the whole partition will be read.

HOraSlowChannel* addChannel(const char* name)

 Adds a channel to the list of channels

void removeChannel(const char* name)

 Removes a channel from the list of channels

void removeAllChannels()

 Removes all channels from the list of channels

HOraSlowChannel* getChannel(const char* name)

 Returns a pointer to the channel objects specified by name

void addHldfileFilter(const char* s)

 Adds a hld-file to the list of hld-files to be applied as filter for output and drawing

void clearHldfileFilter()

 Clears the hld-file filter

Bool_t readArchiverRates()

 Reads the rates of the channel archiver

Bool_t readSummary()

 Reads the summary information for all channels

void writeSummaryToAscii(const char* filename,Int_t opt)

 Writes the periods and the channel summary information to an ASCII file
 option opt 0 = all periods
            1 = only hld-files
            2 = apply hld-file filter
