Class TGo4BackStore

class TGo4BackStore

derived from TGo4EventStore

Field Detail

fbBranchExists

private Bool_t fbBranchExists

True if branch already exists. Used for automatic creation
of new event branch within Store method.

public const static const Text_t[] fgcEVBRANCHNAME

Standard go4 name of the branch used in all treestore
and treesource implementations.

public const static const Text_t[] fgcTREESUF

Standard go4 suffix for tree name

public const static const Int_t fgiMAXAUTOBYTES

Number of bytes for autosave attempt of tree. This specifies when the
tree in memory will be reset, since we do not want to autosave anything here.

private Int_t fiBufsize

buffer size for tree branch.

private Int_t fiFillCount

counter of filled events.

private Int_t fiSplit

TBranch splitlevel.

private TGo4EventElement* fxEvent

Points to event structure to be filled into branch.

public TTree* GetTree()

Access to the Tree structure, for framework

public void Reset()

Dynamic list might reset backstore after processing

public virtual Int_t Store(TGo4EventElement* event)

Stores eventelement event into the storage implementation.

public virtual Int_t Store(TGo4Parameter* cali)
