Class TGo4DynamicList

class TGo4DynamicList

derived from TGo4DynamicEntry

Aggregate which is responsible for the dynamically created analysis objects like histograms. Dynamic list may contain other
dynamic lists, which are processed iteratively.

Field Detail

fxList

private TObjArray* fxList

array to keep the list dynamic list entries

private TIterator* fxListIterator

private TMutex* fxListMutex

mutex protecting the dynamic list

private TFolder* fxTempFolder

temporary folder for status creation

public TGo4DynamicList()

default ctor for streamer.

public TGo4DynamicList(const Text_t* name)

public virtual synchronized ~TGo4DynamicList()

public Bool_t AddEntry(TGo4DynamicEntry* en)

An external dynamic entry object is added to the list. Responsibility for
the entry is passed to the list, i.e. it should not be deleted from outside.

public virtual void CleanupCondition(TGo4Condition* con)

Remove reference to condition con from all dynamic list entries.

public virtual void CleanupEvent(TGo4EventElement* ev)

If event ev matches one internal event, the
reference to event will be reset to 0.
This is used when external event is deleted
to avoid dead pointers. May be overloaded if subclasses
also keep pointers to event structures.

public virtual void CleanupHistogram(TH1* his)

Remove reference to histogram his from all dynamic list entries.

public virtual void Clear(Option_t* option)

Removes all entries and deletes them.

public TGo4DynamicEntryStatus* CreateEntryStatus(const Text_t* name)

Creates an entry status object for entry of name and returns it.

public TGo4DynamicEntryStatus* CreateStatus()

Create a status object containing information such as the object names.
Can be sent to the Display to show the existing objects and their relations.
Memento mechanism is _not_ provided here, since we would not change
the object names afterwards.

public void DeleteEntry(const Text_t* name)

The list entry of name is removed from list; all heap objects are deleted

public TGo4DynamicEntry* GetEntry(const Text_t* name)

Returns the list entry instance of the name

public TNamed* GetObject(const Text_t* name)

Get the object which is kept in the list entry by name. Returns
0 if no such name.

public const Bool_t IsEmpty()

Check if there are any entries in the list

public TGo4DynamicEntry* NextEntry()

Delivers next entry in list. 0 if no more entry

public virtual Int_t Process()

Iterates all entries of the list and processes the objects, depending on coordinate values and analysis condition.

public virtual void Reset()

Resets this entry to an initial status.

public void ResetIterator()

Resets internal list iterator.

public virtual Bool_t SetEntryStatus(const Text_t* name, TGo4DynamicEntryStatus* state)

Set dynamic entry of name to the given entry status.

public virtual void SetStatus(TGo4DynamicEntryStatus* state)

Set this dynamic entry to the values of status object state.

private void UpdateStatus(TGo4DynamicEntryStatus* state)

Create a status object containing information such as the object names.
Can be sent to the Display to show the existing objects and their relations.
Memento mechanism is _not_ provided here, since we would not change
the object names afterwards.
