Member Function Documentation

◆ GetCollection()

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

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

◆ 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

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

◆ operator!=()

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

Compare two iterator objects.

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

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

◆ operator()()

TObject* TIterator::operator() ( )
inline

Definition at line 43 of file TIterator.h.

◆ operator*()

TObject * TIterator::operator* ( ) const

Return current object or nullptr.

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