datapoint

The data point to be added

Definition at line 358 of file BCDataSet.cxx.

void BCDataSet::Dump

(

)

Dump the data to the standard output

Definition at line 385 of file BCDataSet.cxx.

std::vector< double > BCDataSet::GetDataComponents

(

unsigned int BCDataSet::GetNDataPoints

(

)

Returns

The number of data points.

Definition at line 79 of file BCDataSet.cxx.

unsigned int BCDataSet::GetNValuesPerPoint

(

)

Returns

number of values per data point (dimension of data).

int BCDataSet::ReadDataFromFile ( const char *  filename, const char *  treename, const char *  branchnames  )

inline

Reads data from a file. For a description see the following member functions.

Definition at line 96 of file BCDataSet.h.

int BCDataSet::ReadDataFromFileTree	(	const char *	filename,
		const char *	treename,
		const char *	branchnames
	)

Reads a TTree from a .root file. Opens a .root file and gets a TTree. It creates data points containing the values read from the file.

Parameters

filename	The name of the .root file.
treename	The name of the TTree.
branchnames	A list of the names of the branches separated by a comma

Returns

An error code.

int BCDataSet::ReadDataFromFileTxt	(	const char *	filename,
		int	nvariables
	)

Reads data from a .txt file. Opens a .txt file and creates data objects containing the values read from the file.

Parameters

filename	The name of the .txt file.
nvariables	The number of variables.
