Detailed Description

template<class T>
class casa::MarshButterworthBandpass< T >

A Butterworth function class that supports serialization.

Intended use:

Public interface

Prerequisite

Function

Etymology

"Marsh" is short for "Marshallable" which means that the class can be serialized into a form that can be transmitted to another execution context. "ButterBandpass" refers to its parent class: SimButterworthBandpass.

Synopsis

This class is a specialization of SimButterworthBandpass class that supports serialization. That is, it allows one to write the state of the SimButterworthBandpass function object into a Record. This record can then be transmitted to another execution context (e.g. or another AIPS++ DO) where it can be "reconstituted" as a new object with identical state as this one. This documentation focusses on this serialization functionality (also known as "marshalling"); for details about the general features of this Butterworth function, see the SimButterworthBandpass class.

Example

Motivation

Making SimButterworthBandpass Marshallable provides a convenient way of configuring the simulator tool from .

Member Enumeration Documentation

template<class T>

enum casa::MarshButterworthBandpass::FieldNames

definitions of the fields stored in a serialized Record.

The actual string names are stored in FUNCFIELDS

Enumerator:

BPASS	the minimum cutoff, center, and maximum cutoff values
ORDER	the orders of the transitions between pass and no-pass
PEAK	the peak value
NFieldNames	the number of supported fields
