Go4EventServer
Class TGo4TreeStore

class TGo4TreeStore

derived from TGo4EventStore

Storage instance using the central main go4 tree which
is accessible as singleton. Each treestore instance
adds at least one new branch to that tree and fills
it with the data at the event pointer. Branch associated
with this tree store may be written to the main tree file,
or be located in another file which is specified by the
filename parameter of ctor.

Field Detail

fcEventClass

private Text_t[256] fcEventClass

Class name of the event associated with this store.

public const static const Text_t[] fgcFILESUF

Standard suffix for file name

private Int_t fiBufsize

buffer size for tree branch.

private Int_t fiSplit

TBranch splitlevel.

private TBranch* fxBranch

The branch representing our store.

private TGo4EventCalibration* fxCalibration

Points to calibration structure to be filled into branch.

private TGo4EventElement* fxEvent

Points to event structure to be filled into branch.

private TFile* fxFile

Optional file where our branches are located. By
default, branches are written to the same file as the main tree.

private TGo4MainTree* fxSingletonTree

Reference to external tree singleton wrapper instance.
Is initialized once at the start and used to access
the singleton member functions.

private TTree* fxTree

Reference to the external main tree.

public TGo4TreeStore(const char * name, TGo4EventElement* event, Int_t splitlevel, Int_t bufsize, Text_t* filename, Int_t compression)

public TGo4TreeStore()

public TGo4TreeStore(TGo4TreeStoreParameter* par, TGo4EventElement* event)

public virtual synchronized ~TGo4TreeStore()

public void SetCompression(Int_t comp)

Set the file compression level. May be changed on the fly.

public virtual Int_t Store(TGo4EventElement* event)

Stores eventelement event into the storage implementation.
May be a file, a root tree, a socket to a viewer...

public virtual Int_t Store(TGo4Parameter* cali)

Saves a calibration object correllated with the current event into the storage.
This method is optional, i.e. it needs not to be implemented for all subclasses.
