Dear developpers, I have questions concerning TRefArray(Iter).
My use case is the following: I have a class A (inherited from TObject)
that have as data member a
TRefArray* fDigitList;
(plus an index variable)
and a method to fill this TRefArray using
void AddDigit(TObject* a) { fDigitList->Add(a); }
As it is clear the type of object stored in fDigitList are inherited
from TObject but are from different kind.
I would like to Dump the class A, so I am using A->Dump():
==>Dumping object at:8be69e8, name=RTrackElement, class=RTrackElement
fIndex 5
*fDigitList ->8bf22b8
fUniqueID 0 object unique identifier
fBits 50331648 bit field status word
=====> fDigitList: #enties = 5
The last line come from the fact that I have overloaded the A::Dump
method of TObject as
virtual void Dump() const {
TObject::Dump();
if(fDigitList) {
cout << "=====> fDigitList: #enties = " << (fDigitList->GetLast()+1)
<< endl;
TIter next(fDigitList);
TObject* obj;
int iobj = 0;
while( (obj = next()) ) {
cout << "Dump Digit[" << iobj++ << "]" << endl;
obj->Dump();
}
}
}
My problem is that I would like to Dump the content of fDigitList not
only the pointer value. It is the reason of the iteration on the
Tobject stored in it. But as you can see I does not get any "Dump
Digit" message this means that next() return 0 even if the TRefArray is
filled.
Looking at the code (I am using 3.3/05) I have found the method
TObject *TRefArrayIter::Next()
always return 0 because the code is commented!
1) How I can dump the class A content and the TRefArray as well?
2) If I have to iterate on TRefArray how I proceed?
Regards,
Jean-Eric Campagne
