hep::mc_point< T > Class Template Reference

Detailed Description

template<typename T>
class hep::mc_point< T >

A random point \( \vec{x} \in [0,1]^d \) in the \( d \)-dimensional hypercube with an associated weight.

Constructor & Destructor Documentation

mc_point() [1/3]

template<typename T>

hep::mc_point< T >::mc_point ( std::vector< T > const &  point, T  weight = T(1.0)  )

inlineexplicit

Constructor. The weight is computed using the inverse of calls, point determines the location of this point in the hypercube of dimension point.size().

mc_point() [2/3]

template<typename T>

hep::mc_point< T >::mc_point ( mc_point< T > const &  )

delete

There is no copy constructor.

mc_point() [3/3]

template<typename T>

hep::mc_point< T >::mc_point ( mc_point< T > &&  )

delete

There is no move constructor.

~mc_point()

template<typename T>

virtual hep::mc_point< T >::~mc_point ( )

virtualdefault

Destructor.

Member Function Documentation

operator=() [1/2]

template<typename T>

mc_point& hep::mc_point< T >::operator= ( mc_point< T > const &  )

delete

There is no copy assignment operator.

operator=() [2/2]

template<typename T>

mc_point& hep::mc_point< T >::operator= ( mc_point< T > &&  )

delete

There is no move assignment operator.

point()

template<typename T>

std::vector<T> const& hep::mc_point< T >::point ( ) const

inline

The coordinates of this point of the hypercube. The dimension can be obtained using point.size().

weight()

template<typename T>

virtual T hep::mc_point< T >::weight ( ) const

inlinevirtual

The weight \( w \) of this point. The PLAIN integrator (plain) produces points that have weight equals one, i.e. are constant over the entire unit-hypercube. This also means that weight does not include the averaging factor \( 1 / N \) that is used to produce the expected value.

Reimplemented in hep::multi_channel_point2< T, M >.
