Detailed Description

Base class for composable distributions. Responsible for building the final distributions that can be sampled.

Constructor & Destructor Documentation

◆ FComposableDistribution() [1/2]

FComposableDistribution::FComposableDistribution ( )
inlineprotected

Constructor. Protected to prevent instantiating the base class.

◆ ~FComposableDistribution()

FComposableDistribution::~FComposableDistribution ( )
inlineprotected

Destructor.

◆ FComposableDistribution() [2/2]

FComposableDistribution::FComposableDistribution ( const FComposableDistribution &  Other)
inlineprotected

Copy constructor. Protected to only allow type-safe copying.

Member Function Documentation
