protectedvirtual

Add a variable dimension.

Definition at line 96 of file TTreeFormulaManager.cxx.

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 105 of file TTreeFormulaManager.cxx.

◆ EnableMultiVarDims()

void TTreeFormulaManager::EnableMultiVarDims ( )
protectedvirtual

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

inlinevirtual

Definition at line 66 of file TTreeFormulaManager.h.

◆ GetNdata()

Int_t TTreeFormulaManager::GetNdata ( Bool_t  forceLoadDim = kFALSE)
virtual

Return number of available instances in the formulas.

Definition at line 122 of file TTreeFormulaManager.cxx.

◆ Notify()

virtual Bool_t TTreeFormulaManager::Notify ( )
inlinevirtual

This method must be overridden to handle object notification.

Reimplemented from TObject.

Definition at line 68 of file TTreeFormulaManager.h.

◆ operator=()

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

◆ Remove()

void TTreeFormulaManager::Remove ( TTreeFormula adding)
virtual

Definition at line 219 of file TTreeFormulaManager.cxx.

◆ UpdateFormulaLeaves()

void TTreeFormulaManager::UpdateFormulaLeaves ( )
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 291 of file TTreeFormulaManager.cxx.

◆ UpdateUsedSize()

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

Reload the array sizes.
