Class Description

                                                                      
 Frame file direct info data base                                     
                                                                      
 File Info database for simple files                                  
 Uses the standard Framelib                                           
 the TOC of a set of frame files is considered as an info database    
 This allows to treat the same way a small set of frame files         
 and a set of frame files managed by a metadb or a BKDB

Bool_t Open(char* filenames, Option_t* openopt)

 Open the frame files "filenames" considered as an info database

void Close()

 Closes this metadb

Double_t GetStart()

 Returns the start time of the first frame in the files

Double_t GetEnd()

 Returns the end time of the last frame in the metadatabase

void Print(Option_t* opt)

 Prints information about the files

void GetMetaData(VMetaData* meta, Double_t gpstime)

 Retrieve the meta data corresponding to time

void NextMetaData(VMetaData* meta)

 Retrieve the next meta data

void PreviousMetaData(VMetaData* meta)

 Retrieve the previous meta data

void NextMetaData(VMetaData* meta, VConditionSet* condset0)

 Retrieve the next meta data with condition set

void NextMetaData(VMetaData* meta, Double_t time, VConditionSet* condset0)

 Retrieve the next meta data after time "time" with condition set condset

void NextMetaData(VMetaData* meta, Double_t gpstime, VConditionFormula* condf)

 Retrieve the next meta data with time greater or equal to "time"
 selection condition is not taken into account in direct frame access

void NextMetaData(VMetaData* meta, Double_t gpstime, const char* selection)

 Retrieve the next meta data with time greater or equal to "time"
 and selection condition
