Detailed Description

Class defining a plain regular table

Intended use:

Internal

Review Status

Reviewed By:: UNKNOWN

Prerequisite

Etymology

PlainTable represents a plain regular table. This is opposed to a RefTable, which is a view on a PlainTable.

Synopsis

PlainTable is a table consisting of a keyword set and a number of filled and virtual columns. The table control information and the keyword set is stored in an AipsIO file. The data in the filled columns are stored separately by storage managers.
The PlainTable class structure is shown in this UML diagram.

To Do

notify RefTable's when deleting rows

Constructor & Destructor Documentation

◆ PlainTable() [1/4]

casacore::PlainTable::PlainTable	(	SetupNewTable &	,
		rownr_t	nrrow,
		Bool	initialize,
		const TableLock &	lockOptions,
		int	endianFormat,
		const TSMOption &	tsmOption
	)

Construct the object for a new table.

It creates storage manager(s) for unbound columns and initializes all storage managers. The given number of rows is stored in the table and initialized if the flag is set.

◆ PlainTable() [2/4]

casacore::PlainTable::PlainTable	(	MPI_Comm	mpiComm,
		SetupNewTable &	,
		rownr_t	nrrow,
		Bool	initialize,
		const TableLock &	lockOptions,
		int	endianFormat,
		const TSMOption &	tsmOption
	)

MPI version of the constructor.

◆ PlainTable() [3/4]

casacore::PlainTable::PlainTable	(	AipsIO &	,
		uInt	version,
		const String &	name,
		const String &	type,
		rownr_t	nrrow,
		int	option,
		const TableLock &	lockOptions,
		const TSMOption &	tsmOption,
		Bool	addToCache,
		uInt	locknr
	)

Construct the object for an existing table.

It opens the table file, reads the table control information and creates and initializes the required storage managers.

◆ ~PlainTable()

virtual casacore::PlainTable::~PlainTable ( )

virtual

The destructor flushes (i.e.

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

◆ PlainTable() [4/4]

casacore::PlainTable::PlainTable ( const PlainTable & )

private

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

Declaring it private, makes it unusable.

◆ actualTableDesc()

virtual TableDesc casacore::PlainTable::actualTableDesc ( ) const
