Member Function Documentation

int NAIA::SingleTreeChain::Add ( const std::string & filePath )

Add a file to the chain.

Parameters

void NAIA::SingleTreeChain::Clear ( )

Clear all the event information.

SkimTreeHandle< SingleTreeChain > NAIA::SingleTreeChain::CreateSkimTree	(	const std::string &	filename,
		const std::string &	exclBranches
	)

Create a new SkimTree handle object and setup all internal branches.

This will create a new tree in a new root file and will create all the corresponding NAIA branches (except the ones that you excluded). During the event loop you can call SkimTreeHandle::Fill to add the current event to the new tree. After looping you can call SkimTreeHandle::Write to write the new tree to disk.

Parameters
