public abstract class CompositionProduct
extends AbstractIntegrator
```
A class for evaluating the definite integral $∫$ _a^b f(x) E_n (α + β x) dx}. This integral appears as a result of analytically integrating the radiative transfer equation for an absorbing-emitting medium. The number n is the order of this integral, and α and β are the coefficients.
