Detailed Description

MSInterface: A specialization of MSSelectableTable for accessing MS.

Intended use:

Public interface

Etymology

From "ms" and "interface".

Synopsis

A class that can be passed around as MSSelectableTable, with most of the methods overloaded to work with the underlaying MS.

Example

//
// Fill in the expression in the various strings that are passed for
// parsing to the MSSelection object later.
//
String fieldStr,timeStr,spwStr,baselineStr,
uvdistStr,taqlStr,scanStr,arrayStr, polnStr,stateObsModeStr,
observationStr;
baselineStr="1&2";
timeStr="*+0:10:0";
fieldStr="CygA*";
//
// Instantiate the MS and the MSInterface objects.
//
MS ms(MSName),selectedMS(ms);
MSInterface msInterface(ms);
//
// Setup the MSSelection thingi
//
MSSelection msSelection;

msSelection.reset(msInterface,MSSelection::PARSE_NOW,
timeStr,baselineStr,fieldStr,spwStr,
uvdistStr,taqlStr,polnStr,scanStr,arrayStr,
stateObsModeStr,observationStr);
if (msSelection.getSelectedMS(selectedMS))
cerr << "Got the selected MS!" << endl;
else
cerr << "The set of expressions resulted into null-selection";

Motivation

To generalize the implementation of the MSSelection parsers.
