Prerequisite

Etymology

This class is named after Chebyshev Type I polynomials. "Marshallable" means that the class can be serialized into a form that can be transmitted to another execution context.

Synopsis

This class is a specialization of the Chebyshev class that supports serialization. That is, it allows one to write the state of the Chebyshev polynomial object into a Record. This record can then be transmitted to another execution context 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 the Chebyshev polynomial series, see the Chebyshev class.

Example

Motivation

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

Constructor & Destructor Documentation

template<class T>
casacore::MarshallableChebyshev< T >::MarshallableChebyshev ( )
inline

create a zero-th order Chebyshev polynomial with the first coefficient equal to zero.

The bounded domain is [T(-1), T(1)]. The OutOfDomainMode is CONSTANT, and the default value is T(0).

Definition at line 114 of file MarshallableChebyshev.h.

template<class T>
casacore::MarshallableChebyshev< T >::MarshallableChebyshev ( const uInt  n)
inlineexplicit

create an n-th order Chebyshev polynomial with the coefficients equal to zero.

The bounded domain is [T(-1), T(1)]. The OutOfDomainMode is CONSTANT, and the default value is T(0).

const T &  max,
const typename ChebyshevEnums::OutOfIntervalMode  mode = ChebyshevEnums::CONSTANT,
const T &  defval = T(0) 
)
inline

create a zero-th order Chebyshev polynomical with the first coefficient equal to one.

min is the minimum value of its Chebyshev interval, and max is the maximum value. mode sets the behavior of the function outside the Chebyshev interval (see setOutOfIntervalMode() and OutOfIntervalMode enumeration definition for details). defval is the value returned when the function is evaluated outside the Chebyshev interval and mode=CONSTANT.

const T &  max,
const typename ChebyshevEnums::OutOfIntervalMode  mode = ChebyshevEnums::CONSTANT,
const T &  defval = T(0) 
)
inline

create a fully specified Chebyshev polynomial.

coeffs holds the coefficients of the Chebyshev polynomial (see setCoefficients() for details). min is the minimum value of its canonical range, and max is the maximum value. mode sets the behavior of the function outside the Chebyshev interval (see setOutOfIntervalMode() and OutOfIntervalMode enumeration definition for details). defval is the value returned when the function is evaluated outside the canonical range and mode=CONSTANT.
