void TTreeFormulaManager::AddVarDims ( Int_t virt_dim )

protectedvirtual

Add a variable dimension.

Definition at line 97 of file TTreeFormulaManager.cxx.

◆ CancelDimension()

void TTreeFormulaManager::CancelDimension ( Int_t virt_dim )

protectedvirtual

Cancel a dimension.

This is usually called when an out-of-bounds index is used.

Definition at line 106 of file TTreeFormulaManager.cxx.

◆ EnableMultiVarDims()

void TTreeFormulaManager::EnableMultiVarDims ( )

protectedvirtual

Set the manager as handling a formula with multiple variable dimensions.

virtual

Return number of available instances in the formulas.

Definition at line 123 of file TTreeFormulaManager.cxx.

◆ Notify()

virtual Bool_t TTreeFormulaManager::Notify ( )

inlinevirtual

This method must be overridden to handle object notification.

Reimplemented from TObject.

◆ operator=()

TTreeFormulaManager& TTreeFormulaManager::operator= ( const TTreeFormulaManager & )

private

◆ Remove()

void TTreeFormulaManager::Remove ( TTreeFormula * adding )

virtual

This function could be called TTreePlayer::UpdateFormulaLeaves, itself called by TChain::LoadTree when a new Tree is loaded.

Because Trees in a TChain may have a different list of leaves, one must update the leaves numbers in the TTreeFormula used by the TreePlayer.

Definition at line 292 of file TTreeFormulaManager.cxx.

◆ UpdateUsedSize()

void TTreeFormulaManager::UpdateUsedSize	(	Int_t &	virt_dim,
		Int_t	vsize
	)

protectedvirtual
