Detailed Description

GBTMSFeedFiller fills the MSFeed table for GBT fillers.

Intended use:

Internal

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

MeasurementSets
GBT FITS files

Etymology

This class puts GBT data (fills) into the MSFeed table.

Synopsis

This class puts the appropriate values for the GBT in an MSFeed table (which has been previously created as part of a MeasurementSet). On each fill() any necessary additions to the MSFeed are made.

The feedIds are available to be used by other GBTMS*Fillers as other subtables are filled in turn.

Example

Motivation

Writing a filler is a daunting task. There are various dependencies between the subtables. It helps to encapsulate the knowlege and task of filling a specific subtable to separate classes.

Constructor & Destructor Documentation

GBTMSFeedFiller::GBTMSFeedFiller ( )

The default ctor.

No MSFeed table has been attached yet. Calling fill on such a filler will throw an exception. It is present so that this object can be instantiated before an MSFeed has been created.

GBTMSFeedFiller::GBTMSFeedFiller ( MSFeed & msFeed )

A filler attached to an MSFeed table.

GBTMSFeedFiller::~GBTMSFeedFiller ( )

GBTMSFeedFiller::GBTMSFeedFiller ( const GBTMSFeedFiller & other ) [private]

undefined and unavailable

Member Function Documentation

Int GBTMSFeedFiller::addFeed	(	Double	time,
		Double	interval,
		const Matrix< Double > &	offsets,
		const Vector< String > &	polTypes,
		const String &	feedName,
		Int	srFeedId,
		const String &	trckBeam,
		const String &	rxName,
		const Vector< String > &	rcptrNames
	)		`[private]`

add a row with a new feed id given this information return the new feed ID just added.

void GBTMSFeedFiller::attach ( MSFeed & msFeed )

attach it to an MSFeed

Bool GBTMSFeedFiller::checkPrior	(	const GBTFeed &	feed,
		Int	sequence
	)

Use this prior to calling fill on all feeds to be filled.

This checks to see if the previous item at sequence can be reused. If this is false, it also resets the internal feed count anticipating that the subsequent fill will add new rows.

Int GBTMSFeedFiller::feedId ( Int whichFeed ) const

get the feed id corresponding to physical feed id indicated

void GBTMSFeedFiller::fill ( )

fill - using the given keys from other tables this implementation always fills just one feed ID (i.e.

FEED_ID == 0 here) TIME and INTERVAL are both 0.0 - there is no time dependence and there is no spectral window dependence. This is only used by the holography filler since as yet there is no IF information filled for that backend and hence no feed information is available. Only one row will ever be filled by this and this should not be used after the other fill method has been used.

Int GBTMSFeedFiller::fill	(	const GBTFeed &	feed,
		Int	sequence
	)

Add the feeds found here, reusing the previous sequence number if sequence is >= 0.

sequence is not checked for validity. checkPrior should be used to verify that things can be reused. It should be followed by a call to setTime when the mid-point and interval appropriate for the whole scan are known. return the feed ID just filled

void GBTMSFeedFiller::flush ( ) [inline]

flush the underlying MS subtable

String GBTMSFeedFiller::gbtFeedName ( Int feedId ) const

Get the value filled in to the GBT_FEED_NAME column for the indicated FEED_ID value.

Bool GBTMSFeedFiller::hasBeamSwitched ( ) const [inline]

Returns True if any of the filled FEED_IDs are beam-switched pairs.
