◆ ~MorphCacheElem()

RooIntegralMorph::MorphCacheElem::~MorphCacheElem ( )

override

Destructor.

Definition at line 274 of file RooIntegralMorph.cxx.

Member Function Documentation

◆ binX()

Int_t RooIntegralMorph::MorphCacheElem::binX ( double x )

protected

Return the bin number enclosing the given x value.

Definition at line 305 of file RooIntegralMorph.cxx.

◆ calculate()

void RooIntegralMorph::MorphCacheElem::calculate ( TIterator * iter )

Calculate shape of p.d.f for x,alpha values defined by dIter iterator over cache histogram.

Definition at line 316 of file RooIntegralMorph.cxx.

◆ calcX()

double RooIntegralMorph::MorphCacheElem::calcX	(	double	y,
		bool &	ok )

protected

Calculate the x value of the output p.d.f at the given cdf value y.

The ok boolean is filled with the success status of the operation.
