Bool_t _ready ! Are the BranchVector and BranchIdMap ready
vector<pair<KanBranch*,KanPersistable*>,allocator<pair<KanBranch*,KanPersistable*> > > _ownVect ! Vector of KanBranch / KanPersistable pairs
map<const KanBranch*,unsigned short,less<const KanBranch*>,allocator<pair<const KanBranch* const,unsigned short> > > _ownMap ! Map from owner object -> bid
string _collectionName ! The name of the collection
Dna::Scope _scope The scope of this tree
UShort_t _tid This tree's id;
TString _nextFile The File with the successor to this tree
TObjArray _objects Persistent List of Master Obbjects
This sub-class of TTree implements some special functionality for Kanga
and provides an interface for adding/getting Kanga objects to/from TTrees.
On writing the interface is:
aKanTreeBase->addWriteObject(aKanBranch,"BranchName");
This will create a new branch (and it's sub-branches) on the tree
On reading the interfaces is:
KanBranch* branchPtr(0);
aKanTreeBase->getReadObject("BranchName",branchPtr)
branchPtr will be set to the address used by ROOT to read in the
KanBranch object
KanTreeBase also manages part of the persistent object look up from KanID:
aKanTreeBase->findObj(UShort_t bid, UShort_t oid)
will return the object with id TreeID:bid:oid for the current event,
if that object has already by read in
aKanTreeBase->getObj(UShort_t bid, UShort_t oid)
will return the object with id TreeID:bid:oid for the current event,
and will acutally read the branch if the object has not been read yet
