Detailed Description

Class to view a concatenation of tables as a single table.

Intended use:

Internal

Review Status

Reviewed By:
UNKNOWN

Prerequisite

Etymology

ConcatTable represents the concatenation of one or more tables.

Synopsis

ConcatTable is used to virtually concatenate one or more tables. Those tables must have the same description.

It acts to the user as a normal table. All gets and puts are handled by ConcatColumn which directs them to the referenced columns while (if needed) converting the given row number to the row number in the referenced tables. For that purpose ConcatTable keeps the number of rows in the referenced tables.
Note: Currently it cannot handle changes in the number of rows in the underlying tables;

It is possible to specify the keyword names of the subtables that have to be concatenated as well. The other subtables are assumed to be identical for all tables, so only the subtable of the first table is used.

The ConcatTable maintains its own keyword set, which is initially a copy of the keyword set of the first table. It replaces the keywords of the subtables to be concatenated. The keyword set is not persistent. One can add or change keywords, but these changes are not kept when the ConcatTable object is made persistent.

Motivation

Sometimes a very large MeasurementSet is split into multiple smaller ones using the time axis. Using ConcatTable they can still be viewed as a single MS. The SYSCAL subtable is split in time as well, thus it has to be possible to concatenate that one as well.
Note: An MS split in subband could be concatenated as well provided that at least the first part contains the full SPECTRAL_WINDOW subtable and that unique SPWids are used;

Constructor & Destructor Documentation

◆ ConcatTable() [1/4]

casacore::ConcatTable::ConcatTable ( const Block< Table > &  tables,
const Block< String > &  subTables,
const String subDirName 
)

Create a virtual table as the concatenation of the given tables.

It checks if the table descriptions of the tables are the same. Subtables with the given names will be concatenated as well. It is assumed that the other subtables are the same for all tables, so the ones of the first table are used.
The option can be Table::Old or Table::Update.
If a non-empty subdirectory name is given, the tables will be moved to that subdirectory when the concatenated table is written (by writeConcatTable).

◆ ConcatTable() [2/4]

casacore::ConcatTable::ConcatTable ( const Block< String > &  tableNames,
const Block< String > &  subTables,
const String subDirName,
int  option,
const TableLock lockOptions,
const TSMOption tsmOption 
)

◆ ConcatTable() [3/4]

casacore::ConcatTable::ConcatTable ( AipsIO ,
const String name,
rownr_t  nrrow,
int  option,
const TableLock lockOptions,
const TSMOption tsmOption 
)

Create a concat table out of a file (written by writeConcatTable).

The referenced tables will also be opened (if not stored in the cache).

◆ ~ConcatTable()

virtual casacore::ConcatTable::~ConcatTable ( )
virtual

The destructor flushes (i.e.

writes) the table if it is opened for output and not marked for delete.

◆ ConcatTable() [4/4]

casacore::ConcatTable::ConcatTable ( const ConcatTable )
private

Copy constructor is forbidden, because copying a table requires some more knowledge (like table name of result).

Declaring it private, makes it unusable.
