Detailed Description

A top level class defining the data handling interface for the flagging module.

Intended use:

Public interface

Prerequisite

Etymology

FlagDataHandler stands for generic data handling (i.e. MSs, CalTables, ...) specific to the flagging module

Synopsis

This is a top-level class defining the data handling interface for the flagging module. There are various methods (virtual) that must be re-implemented by the specific derived classes (e.g. FlagMSHandler, FlagCalTableHandler). These methods essentially cover:

Table access (i.e. open/close/iteration/rw)

Table selection (i.e. expression parsing, sub-table selection)

Additionally there are public non-virtual methods to:

Set configuration parameters (pre-sort columns, data selection, time interval, async I/O)

Enable and access different kinds of mapping (baselines, correlation products, antenna pointing)

Also at this top level there are public members which are used by the FlagAgent classes, so that there is no dependency with the specific implementation classes (e.g. FlagMsHandler, FlagCalTableHandler), and thus no re-implementation is required at the FlagAgent level.

VisBuffer (for accessing the data and meta data columns)

Chunk and Table flag counters (for statistics)

Motivation

The motivation for the FlagDataHandler class is having all the data operations encapsulated in one single class, with a common interface for all types of tables (MSs, CalTables, SingleDish), so that no specific specific table type implementation has to be done at the FlagAgent level.

Example

    // The following code sets up a FlagDataHandler with either CalTable or MS implementation and
    // iterates through the table applying a clip agent, flushing the flags, and extracting summaries.
   
    // IMPORTANT NOTE:
    // The order of FlagDataHandler and FlagAgent initialization is critical to have everything right,
    // in particular data selection must happen before initializing FlagAgents, and iterator generation
    // must be done after initializing FlagAgents, so that each agent can communicate to the FlagDataHandler
    // which columns have to be pre-fetched (async i/o or parallel mode), and what mapping options are necessary.
   
    // NOTE ON ASYNC I/O:
    // Asyncnronous I/O is only enabled for MS-type tables, but not for CalTables, and it is necessary to switch
    // it on before generating the iterators. Something else to take into account, is that there are 2 global
    // switches at .casarc level which invalidate the application code selection:
    //
    // VisibilityIterator.async.enabled rules over
    // |-> FlagDataHandler.asyncio, and in turns rules over
    //     |-> FlagDataHandler.enableAsyncIO(True)
   
    // Identify table type
    Table table(msname_p,TableLock(TableLock::AutoNoReadLocking));
    TableInfo& info = table.tableInfo();
    String type=info.type();
   
    // Create derived FlagDataHandler object with corresponding implementation
    FlagDataHandler *fdh_p = NULL;
    if (type == "Measurement Set")
    {
       fdh_p = new FlagMSHandler(msname_p, FlagDataHandler::COMPLETE_SCAN_UNMAPPED, timeInterval_p);
    }
    else
    {
       fdh_p = new FlagCalTableHandler(msname_p, FlagDataHandler::COMPLETE_SCAN_UNMAPPED, timeInterval_p);
    }
   
    // NOTE: It is also possible to independently set the iteration approach via the setIterationApproach
    //       method which accepts the following modes, defined in the FlagDataHandler iteration enumeration
    //
    //       COMPLETE_SCAN_MAPPED:
    //       - Sort by OBSERVATION_ID, ARRAY_ID, SCAN_NUMBER, FIELD_ID, DATA_DESC_ID and TIME
    //       - Group all time steps together, so that there is no sub-chunk iteration

    fdh_p->close();

    agentList.clear();

Example

    // The following code shows the FlagAgent-FlagDataHandler interaction works internally:
   
    // First of all, at construction time, each agent has to communicate to the FlagDataHandler
    // which columns have to be pre-fetched (for async i/o or parallel mode) and what mapping
    // options are necessary
   
    // ...for instance in the case of FlagAgentShadow we need Ant1,Ant2,UVW,TimeCentroid and PhaseCenter:
    flagDataHandler_p->preLoadColumn(vi::Antenna1);
    flagDataHandler_p->preLoadColumn(vi::Antenna2);
    flagDataHandler_p->preLoadColumn(vi::uvw);
    flagDataHandler_p->preLoadColumn(vi::TimeCentroid);
    flagDataHandler_p->preLoadColumn(vi::PhaseCenter);
   
    // ...and FlagAgentElevation needs to have the antenna pointing information globally available for each chunk:
    flagDataHandler_p->setMapAntennaPointing(true);
   
    // Then, at iteration time, the FlagAgentBase class has access to the VisBuffer held
    // in the FlagDataHandler, in order to retrieve the meta-data columns needed for the
    // data selection engine (agent-level row filtering).
    // NOTE: The VisBuffer is actually held within an auto-pointer wrapper,
    //       thus there is an additional get() involved when accessing it.
   
    if (spwList_p.size())
    {
       if (!find(spwList_p,visibilityBuffer_p->get()->spectralWindow())) return false;
    }
   
    // The sorting columns used for the iteration are also accessible to optimize the selection engine:
    // (e.g.: If scan is constant check only 1st row)
    if ( (scanList_p.size()>0) and (find(flagDataHandler_p->sortOrder_p,MS::SCAN_NUMBER)==true) )
    {
       if (!find(scanList_p,visibilityBuffer_p->get()->scan()[0])) return false;
    }
   
    // Once that chunk/rows are evaluated as eligible for the flagging process
    // by the data selection engine, the previously booked maps at construction
    // time can be access in order to iterate trough the data as desired:
    // e.g.: Baseline (antenna pairs) iteration
    for (myAntennaPairMapIterator=flagDataHandler_p->getAntennaPairMap()->begin();
         myAntennaPairMapIterator != flagDataHandler_p->getAntennaPairMap()->end();
         ++myAntennaPairMapIterator)
    {
       // NOTE: The following code is also encapsulated in the FlagAgentBase::processAntennaPair(Int antenna1,Int antenna2) code
   
       // From the antenna map we can retrieve the rows corresponding to the baseline defined by the antenna pair
       vector<uInt> baselineRows = (*flagDataHandler_p->getAntennaPairMap())[std::make_pair(antennaPair.first,antennaPair.second)];
   
       // This rows can be now inserted in the mapper classes (VisMapper and FlagMapper using the CubeView<T> template class)
       VisMapper visibilitiesMap = VisMapper(expression_p,flagDataHandler_p->getPolarizationMap());
       FlagMapper flagsMap = FlagMapper(flag_p,visibilitiesMap.getSelectedCorrelations());
       setVisibilitiesMap(antennaRows,&visibilitiesMap);
       setFlagsMap(antennaRows,&flagsMap);
    }
   
    // Finally, after flagging time, the FlagAgent can communicate to the FlagDataHandler
    // that the modified FlagCube has to be flushed to disk, this is a small but very important
    // step in order to avoid unnecessary I/O activity when a chunk is not eligible for flagging
    // or the auto-flagging algorithms don't produce any flags.
   
    // If any row was flag, then we have to flush the flagRow
    if (flagRow_p) flagDataHandler_p->flushFlagRow_p = true;
    // If any flag was raised, then we have to flush the flagCube
    if (visBufferFlags_p>0) flagDataHandler_p->flushFlags_p = true;
