Detailed Description

A Table intended to hold a MeasurementSet POLARIZATION table.

Intended use:

Part of API

Prerequisite

MeasurementSet MSTable

Etymology

MSPolarization stands for the MeasurementSet Polarization table.

Synopsis

An MSPolarization is a table intended to hold the POLARIZATION table for the MeasurementSet. It has an identical set of member functions as the main MeasurementSet class, except (currently) for the default calibration members. For further info and examples see the MeasurementSet class.

Example

See the MeasurementSet for an example of how to access and use this class.

Motivation

It was found that subtables and the main table of the MeasurementSet have a lot in common, therefore they derive their interface from the same base class. Each subtable has its own class to keep the enum definitions and conversion functions in separate scopes.

To Do

MeasurementSet.

Constructor & Destructor Documentation

casa::MSPolarization::MSPolarization

(

)

This constructs an empty MSPolarization.

casa::MSPolarization::MSPolarization	(	const String &	tableName,
		TableOption	= Table::Old
	)

These constructors mirror the Table ones with additional checking on validity (verifying that the MSPolarization will have the required columns and keywords) An exception is thrown if the constructed Table is not a valid MSPolarization.

Thrown Exceptions

• AipsError

casa::MSPolarization::MSPolarization	(	const String &	tableName,
		const String &	tableDescName,
		TableOption	= Table::Old
	)

casa::MSPolarization::MSPolarization	(	SetupNewTable &	newTab,
		uInt	nrrow = 0,
		Bool	initialize = False
	)

casa::MSPolarization::~MSPolarization

(

)

As with tables, the destructor writes the table if necessary.

Additional checking is done here to verify that all required columns are still present. If it is NOT valid, it will write the table and then throw an exception.

Thrown Exceptions

• AipsError

casa::MSPolarization::MSPolarization	(	const String &	tableName,
		TableOption	= Table::Old
	)

These constructors mirror the Table ones with additional checking on validity (verifying that the MSPolarization will have the required columns and keywords) An exception is thrown if the constructed Table is not a valid MSPolarization.

Member Function Documentation

MSPolarization& casa::MSPolarization::operator=

(

const MSPolarization &

)

Assignment operator, reference semantics.

MSPolarization casa::MSPolarization::referenceCopy	(	const String &	newTableName,
		const Block< String > &	writableColumns
	)			const

Make a special copy of this Table which references all columns from this Table except those mentioned; those are empty and writable.

Each forwarded column has the same writable status as the underlying column. The mentioned columns all use the AipsIO storage manager. This function is inherited from MSTable and unlikely to be of use, except in the class MeasurementSet (see comment there).\.

Reimplemented from casa::MSTable< ColEnum, KeyEnum >.

static void casa::MSPolarization::init

(

)

[static]

Initialize the statics appropriately.

This does not need to be called by users, it is called by the implementation class MSTableImpl.
