TDrawFeedback Class Reference

Utility class to draw objects in the feedback list during queries.

Draws histograms in separated canvases and user-defined objects via Draw(). Users requiring advanced treatment should implement their own version following this example. See also TStatsFeedback.

Display feedback.

Definition at line 93 of file TDrawFeedback.cxx.

GetName()

const char * TDrawFeedback::GetName ( ) const

inlinevirtual

Returns name of object.

This default method returns the class name. Classes that give objects a name should override this method.

Reimplemented from TObject.

Definition at line 50 of file TDrawFeedback.h.

Hash()

ULong_t TDrawFeedback::Hash ( ) const

inlinevirtual

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

Reimplemented from TObject.
