Detailed Description

Used to concatenate simple GBT tables.

Intended use:

Internal

Review Status

Date Reviewed:

yyyy/mm/dd

Prerequisite

• GBTBackendFiller

Etymology

This contains a Table to which other Tables can be appended. Its quite simple and it it used by the GBTBackendFillers.

Synopsis

Example

Motivation

The GBT backend FITS files generally have ancilliar tables such as PHASE and RECEIVER. In the resulting MS, these are just appended to the end of a subtable. This class contains those subtables and does the appending.

With MS 2, this is somewhat more complicated and hence this class probably needs a better name.

To Do

• Is there a mechanism in the Table system which essentially already does this?

Constructor & Destructor Documentation

GBTSimpleTable::GBTSimpleTable	(	const String &	tableName,
		const String &	indexColumn = String("")
	)

open an already existing table, use the optional index column

GBTSimpleTable::GBTSimpleTable	(	Table &	attachTable,
		const String &	attachKeywordName,
		const String &	tableName,
		const String &	indexColumn = String("")
	)

create a new, empty table attached to the given table at the given keyword name, supply an optional index column

Member Function Documentation

void GBTSimpleTable::add

(

const Table &

other

)

append the given table to the end of this table adding columns as required, any columns with the same name must have the same type and dimensionality

void GBTSimpleTable::add	(	const RecordInterface &	other,
		Bool	nextIndex = True
	)

append this record to the end of this table.

Each field in the record maps to a column in the the table. There must be no subrecords. The types of the fields must match that in the existing table. Fields not already in the table will result in new columns for that table

void GBTSimpleTable::attachIndexCol

(

const String &

indexColumn

)

[private]

void GBTSimpleTable::checkRecord

(

const RecordInterface &

other

)

[private]

this checks the record and adds columns as required

void GBTSimpleTable::flush

(

)

[inline]

flush this table
