Detailed Description

template<typename PointType, size_t Ndims = 9>
class Belle2::MLHANDOVER_NAME< PointType, Ndims >

SelectionVariable that is used for the Machine Learning (ML) based filters.

Does nothing else than handing over the 3x3 git coordinates to the MLRange, where all the ML magic happens. This has to be done this way since this class provides only a static function and we need different instances of ML classifiers. We do however have access to the constructor of the Range classes.

Member Function Documentation

value() [1/2]

static variableType value ( const PointType &  arg1, const PointType &  arg2  )

inlinestaticinherited

Static method that return the variable associated to:

Parameters

arg1	first object of the pair
arg2	second object of the pair

N.B. this method must be static.

value() [2/2]

static std::array<double, Ndims> value ( const PointType &  innerHit, const PointType &  centerHit, const PointType &  outerHit  )

inlinestatic

Getter for coordinate values of the three hits used in a three hit filter.

Parameters

innerHit	: the inner hit
centerHit	: the center hit
outerHit	: the outer hit

Returns

array containing the coordinates of the three hits in the order x, y, z for inner, x, y, y for center, outer
