Go4DynamicList
Class TGo4DynamicEntry

Direct Known Subclasses:

TGo4DynamicList, TGo4HistogramEntry, TGo4TreeHistogramEntry

class TGo4DynamicEntry

derived from TNamed

ABC for all entries that can be kept in a dynamic list.
The Dynamic list itself is a dynamic entry, too; thus
the analysis can handle a dynamic list containing
dynamic sub-lists of histograms.

Field Detail

fbPointerInitDone

protected Bool_t fbPointerInitDone

True if pointers to external objects have already been
initialized. Flag is set by InitPointers() and reset by Reset().

protected Bool_t fbProcessEntry

True if object shall be processed by main event loop automatically.
For example, histogram autofill from event index values.

Text to indicate that no condition is used

public const static const Text_t[] fgcNOEVENT

Text to indicate that no condition is used

public const static const UInt_t fguMAXCONDIMENSION

private Float_t* [2] fxConDataFloat

Array of pointers to the data that is tested against condition.
Used if data is Float_t

private Int_t* [2] fxConDataInt

Array of pointers to the data that is tested against condition.
Used if data is Int_t

private Long_t* [2] fxConDataLong

Array of pointers to the data that is tested against condition.
Used if data is Long_t

private Short_t* [2] fxConDataShort

Array of pointers to the data that is tested against condition.
Used if data is Short_t

private TGo4Condition* fxCondition

Condition to be checked on processing this entry.

private TString fxConditionName

Name of the condition to be applied for this entry.

private TGo4EventElement* [2] fxConEvent

Array of pointers to the event structure that
contains the data for the condition test.

private TString[2] fxConEventName

Array of names of the events which contain
the data members to be tested with the x,y
coordinates of the condition.

private TString[2] fxConVarName

Name of the eventstructure datamembers that shall be
tested with the condition.

public TGo4DynamicEntry()

default ctor for streamer.

public TGo4DynamicEntry(const Text_t* name)

public synchronized ~TGo4DynamicEntry()

public void CleanupCondition(TGo4Condition* con)

If condition con matches the internal condition, the
reference to internal condition will be reset to 0.
This is used when external condition is deleted
to avoid dead pointers.

public 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 void CleanupHistogram(TH1* his)

If histogram his matches the internal histogram, the
reference to internal histogram will be reset to 0.
This is used when external histogram is deleted
to avoid dead pointers. Dummy implementation here!

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 EnableProcessing(Bool_t on)

Switch the autoprocessing state of this entry.

protected TDataMember* FindDataMember(TClass* eventclass, const Text_t* memname, Long_t* totaloffset)

Find out address totaloffset of datamember memname relative to "this" pointer
of eventclass object. Datamember object is returned.
This method is able to treat inherited members. Later on, also aggregates?

public void InitPointers()

Initialize the pointers to external objects. The external objects
(e.g. condition, histogram, data) will be searched by name
in the Go4 folders.

protected Int_t Membersize(const Text_t* name)

find out size of type "name" on runtime for all supported types

public Int_t Process()

Process the dynamic entry.

public void Reset()

Resets this entry to an initial status.

public void SetConditionName(const Text_t* name)

Set name of the external condition to be referenced.

public void SetConEventName(UInt_t ix, const Text_t* name)

Set Name of the eventstructure object that is to be
tested by the condition for axis number ix. ix is 0 for x-axis,
1 for y-axis, etc.

public void SetConVarName(UInt_t ix, const Text_t* name)

Set Name of the data value (eventclass member) that is to be
tested by condition for axis number ix. ix is 0 for x-axis,
1 for y-axis, etc.

public void SetStatus(TGo4DynamicEntryStatus* state)

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

public Bool_t TestCondition()

Test if condition for this entry is true.

protected void UpdateStatus(TGo4DynamicEntryStatus* state)

Update the 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.
