Detailed Description

A class to provide easy read-only access to MSFeed columns.

Public interface

Prerequisite

Etymology

ROMSFeedColumns stands for Read-Only MeasurementSet Feed Table columns.

Synopsis

This class provides read-only access to the columns in the MSFeed Table. It does the declaration of all the Scalar and ArrayColumns with the correct types, so the application programmer doesn't have to worry about getting those right. There is an access function for every predefined column. Access to non-predefined columns will still have to be done with explicit declarations. See ROMSColumns for an example.

Motivation

See MSColumns for the motivation.

Int casacore::ROMSFeedColumns::matchFeed	(	Quantum< Double > &	newTimeQ,
		Quantum< Double > &	newIntervalQ,
		const Int &	antId,
		const Int &	fId,
		const Int &	spwId,

		const Quantum< Double > &	focusLengthQ = `Quantum< Double >()`
	)

Returns the last row that contains a feed with the specified values.

If no matching row can be found, but a match is possible if the validity time interval is widened, return that row and the suggestion for the new time information. If no change to time is necessary, newTimeQ and newIntervalQ are zero. Returns -1 if no match could be found. Ignore the Feed table rows contained in vector ignoreRows. focusLengthQ is only compared if this optional column is present and if the value of focusLengthQ is not dimensionless.

uInt casacore::ROMSFeedColumns::nrow ( ) const

inline

Convenience function that returns the number of rows in any of the columns.
