Member Function Documentation

◆ GetCollection()

virtual const TCollection* TIterator::GetCollection ( ) const
pure virtual

Implemented in TTreeFriendLeafIter, TBtreeIter, RooLinkedListIterImpl, TListIter, RooLinkedListIter, TMapIter, TObjArrayIter, TRefArrayIter, THashTableIter, TIteratorToSTLInterface< STLContainer >, TViewPubFunctionsIter, TOrdCollectionIter, TViewPubDataMembersIter, RooMultiCatIter, RooAbsCategoryLegacyIterator, and RooDataHistSliceIter.

◆ GetOption()

virtual Option_t* TIterator::GetOption ( ) const
inlinevirtual

Reimplemented in TTreeFriendLeafIter, and TListIter.

Definition at line 40 of file TIterator.h.

◆ Next()

virtual TObject* TIterator::Next ( )
pure virtual

◆ operator!=()

Bool_t TIterator::operator!= ( const TIterator &  ) const
virtual

Compare two iterator objects.

For backward compatibility reasons we have to provide this default implementation.

TObject* TIterator::operator() ( )
inline

Definition at line 43 of file TIterator.h.

◆ operator*()

TObject * TIterator::operator* ( ) const
