Member Function Documentation

template<typename VarType >

void KVTreeVectorBranchHandler::AddVectorBranch	(	TTree *	t,
		const std::string &	var
	)

inline

Add a branch to the tree in order to store a vector of values

Template Parameters

VarType type of variable in vector (int, float and double can be used)

Parameters

[in]	t	pointer to the TTree
[in]	var	name to be used for the new branch

Example of use:

AddVectorBranch<int>(t, "Z");

AddVectorBranch<double>(t, "E");

void KVTreeVectorBranchHandler::ClearVectorBranches ( )

inline

Clear all vectors contained in branches, ready to treat a new event

template<typename VarType >

void KVTreeVectorBranchHandler::FillVectorBranch	(	const std::string &	var,
		VarType	val
	)

inline

Add a value to the vector contained in the named branch

Template Parameters

VarType type of variable in vector (int, float and double can be used)

Parameters

[in]	var	name of branch
[in]	val	value to add to vector

Example of use:

KVNucleus& nuc; // reference to a nucleus in an event
FillVectorBranch("Z", nuc.GetZ());
FillVectorBranch("E", nuc.GetE());
