Detailed Description

Base class for objects representing one full entry of a tree (e.g. Event).

A derived class of TreeEntry typically owns multiple Singlets, Containers, as well as its own primitive branches.

Member Function Documentation

§ book()

void panda::TreeEntry::book	(	TTree &	tree,
		utils::BranchList const &	= `{"*"}`
	)

finalvirtual

Book new branches bound to this object on the tree.

Parameters

tree
blist	List of branches to book. Vetoed or unmentioned branches are not booked.

Reimplemented from panda::Object.

§ fill()

Int_t panda::TreeEntry::fill ( TTree & tree )

finalvirtual

Fill a tree.

In most of the objects this will just call tree.Fill(). The function takes care of the case with e.g. Collection where internal address can change after the call to book().

Parameters

tree

Reimplemented from panda::Object.

§ getBranchNames()

panda::utils::BranchList panda::TreeEntry::getBranchNames	(	Bool_t	fullName = `kTRUE`,
		Bool_t	direct = `kFALSE`
	)		const

finalvirtual

Get the full list of branch names.

Parameters

fullName	If true, prepend "(object name)."
direct	If true, return only direct branches of this object (relevant only for TreeEntry)

Reimplemented from panda::Object.

§ getEntry()

Int_t panda::TreeEntry::getEntry	(	UInt_t	treeId,
		Long64_t	entry,
		Bool_t	localEntry = `kFALSE`
	)

finalvirtual

Read an entry from an input tree.

Parameters

treeId	Index of the tree in the inputBranches_ vector.
entry	Entry number in the input tree.
localEntry	If true, entry must be the local entry number of the current tree (i.e. return value of LoadTree)

If localEntry is false, calls tree.LoadEntry(entry).

Returns: Number of bytes read.

Reimplemented from panda::ReaderObject.

§ setAddress()

UInt_t panda::TreeEntry::setAddress	(	TTree &	tree,
		utils::BranchList const &	= `{"*"}`,
		Bool_t	setStatus = `kTRUE`
	)

finalvirtual

Bind the tree branches to the elements of this object.

Parameters

tree
blist	List of branches to bind. Vetoed or unmentioned branches are not bound.
setStatus	If true, set the status of the branch to true before binding.

Returns: Index of the bound tree in the inputBranches_ vector.

Reimplemented from panda::Object.

§ setStatus()

void panda::TreeEntry::setStatus	(	TTree &	tree,
		utils::BranchList const &
	)

finalvirtual

Set status of branches to true (matching branch) or false (vetoed branch)

Sets the status of the branch to true (branch is in the list) or false (branch is vetoed in the list). Branches not mentioned in the branch list are untouched.

Parameters

tree
blist	List of branches. The status of a branch is set to true (false) if BranchName::in(blist) (BranchName::vetoed(blist)) evaluates to true for the branch.

Reimplemented from panda::Object.
