Member Function Documentation

◆ constructArray()

void constructArray ( double  lowerBound,
double  upperBound,
Width< I >  nBinOverlap = 0,
Width< I >  nBinWidth = 0 
)
inlineinherited

Construct the discrete value array at coordinate index I.

This function is only applicable for discrete axes. For continuous axes assignArray should be call with an array containing only the lower and upper bound of the axes range and an optional overlap.

Parameters
lowerBoundLower bound of the value range
upperBoundUpper bound of the value range
nBinOverlapOverlap of neighboring bins. Default is no overlap. Usuallly this is counted in number of discrete values
nBinWidthWidth of the bins at lowest level. Default is width of 1. Usually this is counted in numbers of discrete values

Definition at line 104 of file BoxDivisionHoughTree.h.

◆ fillAll()

void fillAll ( )
inlineprivate

Fill the tree till all nodes are touched once.

This is not for finding results, but for debug reasons.

Definition at line 171 of file DebugableSimpleBoxDivisionHoughTree.h.

◆ writeDebugInfoToFile()

void writeDebugInfoToFile ( const std::string &  filename)
inline

Write out some debug information to a ROOT file with the given name.

This must be done before felling the tree. Attention: This will delete a ROOT file with the same name if already present.

Parameters
filenameThe ROOT filename.
