Member Function Documentation

exec()

virtual DBTable TRestDataBase::exec ( std::string  cmd )

inlinevirtual

return a table from query std::string cmd

Definition at line 100 of file TRestDataBase.h.

get_lastrun()

int TRestDataBase::get_lastrun ( )

virtual

get the latest run id in database

get the latest run in database

Get the latest run in database, by reading the file: $REST_USER_PATH/runNumber. Note that this file saves run number of the next run. So it returns The run number -1.

Definition at line 154 of file TRestDataBase.cxx.

Initialize()

void TRestDataBase::Initialize ( )

virtual

default: read the dataURL file

Definition at line 66 of file TRestDataBase.cxx.

print()

virtual void TRestDataBase::print ( std::string  cmd )

inlinevirtual

print the table after query std::string cmd

Definition at line 98 of file TRestDataBase.h.

query_data()

DBEntry TRestDataBase::query_data ( DBEntry  _info )

virtual

metadata management interface ////////////////////// return the piece of data in fMetadataEntries

The following specification of DBEntry's content means to match any: id <= 0, type == "" ,usr == "" ,tag == "" ,description == "" ,version == "". If all of them mean any, it will return a blank list.

Definition at line 209 of file TRestDataBase.cxx.

query_run()

virtual DBEntry TRestDataBase::query_run ( int  runnumber )

inlinevirtual

run number management interface ////////////////////// return the run number of the run. If not exist, return 0

Definition at line 104 of file TRestDataBase.h.

query_run_file()

virtual DBFile TRestDataBase::query_run_file ( int  runnumber, int  fileid  )

inlinevirtual

return file of certain file id in certain run

Definition at line 106 of file TRestDataBase.h.

query_run_files()

virtual std::vector< DBFile > TRestDataBase::query_run_files ( int  runnumber )

inlinevirtual

return all the files of the run

Definition at line 108 of file TRestDataBase.h.

search_run()

virtual std::vector< int > TRestDataBase::search_run ( DBEntry  info )

inlinevirtual

search runs according to the run info. return a list of run numbers

Definition at line 111 of file TRestDataBase.h.

search_run_with_file()

virtual std::vector< int > TRestDataBase::search_run_with_file ( std::string  filepattern )

inlinevirtual

search runs according to the file name. return a list of run numbers

Definition at line 113 of file TRestDataBase.h.

set_data()

virtual int TRestDataBase::set_data ( DBEntry  info, bool  overwrite = true  )

inlinevirtual

add/update a new record of metadata in database

Definition at line 127 of file TRestDataBase.h.

set_run()

int TRestDataBase::set_run ( DBEntry  info, bool  overwrite = true  )

virtual

add/update a run, with run info as struct DBEntry. returns the added run id

add a new run, with run info as struct DBEntry. returns the added run id

runs are added according to info.id of input DBEntry object: -1 --> do not add 0 --> append a new run in run list >0 --> directly use this run number, overwrite existing

It will write to the file: $REST_USER_PATH/runNumber is writable. The number written will be the next run number

The method in derived class shall follow this rule.

Definition at line 183 of file TRestDataBase.cxx.

virtual int TRestDataBase::set_runfile ( int  runnumber, std::string  filename  )

inlinevirtual

add/update a runfile to the specified run

Definition at line 121 of file TRestDataBase.h.

test()

virtual void TRestDataBase::test ( )

inlinevirtual

test function

Definition at line 96 of file TRestDataBase.h.
