Detailed Description

GBTMSFieldFiller fills the MSField table for GBT fillers.

Intended use:

Internal

Prerequisite

GBT FITS files

Etymology

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

Synopsis

This class puts the appropriate values for the GBT in an MSField table (which has been previously created as part of a MeasurementSet). On each fill() any necessary additions to the MSField are made. This is fully indexed. New rows are only added for each new NAME, CODE, NUM_POLY, SOURCE_ID combination or when the directions change for an existing such combination.

The fieldId is 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

GBTMSFieldFiller::GBTMSFieldFiller ( )

The default ctor.

No MSField 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 MSField has been created.

GBTMSFieldFiller::GBTMSFieldFiller ( MSField & msField )

A filler attached to an MSField table.

GBTMSFieldFiller::~GBTMSFieldFiller ( )

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

undefined and unavailable

Member Function Documentation

void GBTMSFieldFiller::attach ( MSField & msField )

attach it to an MSField

const Int& GBTMSFieldFiller::fieldId ( ) const [inline]

this is the row numbers of the most recently filled MSField row it returns -1 if nothing has been filled yet

Definition at line 118 of file GBTMSFieldFiller.h.

References fieldId_p.

void GBTMSFieldFiller::fill	(	Int	sourceId,
		const String &	name,
		const MDirection &	fieldDir
	)

fill, adding rows as necessary, fieldDir is the nominal pointing direction at equinox.

DELAY_DIR, PHASE_DIR, and REFERENCE_DIR are set to the fieldDir value. These are always in J2000 in the MS.

void GBTMSFieldFiller::flush ( ) [inline]

flush the underlying MS subtable

void GBTMSFieldFiller::init ( MSField & msField ) [private]

initialize the above for the first time
