Member Function Documentation

◆ GetCollection()

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

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

◆ GetOption()

virtual Option_t * TIterator::GetOption ( ) const
inlinevirtual

Reimplemented in TListIter, and TTreeFriendLeafIter.

Definition at line 40 of file TIterator.h.

◆ Next()

virtual TObject * TIterator::Next ( )
pure virtual

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

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

◆ operator()()

TObject * TIterator::operator() ( )
inline

Definition at line 43 of file TIterator.h.

◆ operator*()

TObject * TIterator::operator* ( ) const
virtual

Return current object or nullptr.

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