		InputIterator	last
	)

inherited

Assign from iterators.

Parameters

first	The start of the range to put in the container.
last	The end of the range to put in the container.

Any existing owned elements will be released. The DataVector's ownership policy determines whether it will take ownership of the new elements.

◆ assign() [2/2]

template<class T , class BASE >

void DataVector< T, BASE >::assign ( std::initializer_list< value_type > l )

inherited

Parameters

l	An initializer list.

Any existing owned elements will be released. The DataVector's ownership policy determines whether it will take ownership of the new elements.

◆ assignBaseElement()

template<class T , class BASE >

void DataVector< T, BASE >::assignBaseElement	(	typename BaseContainer::iterator	pos,
		typename BaseContainer::value_type	newElem
	)

privateinherited

Handle element assignment from a base pointer.

Parameters

pos	Position in the container to assign.
newElem	The new element to assign.

The old element is freed if this container owns elements. Auxiliary data are copied if appropriate.

◆ assignElement() [1/2]

template<class T , class BASE >

void DataVector< T, BASE >::assignElement	(	typename BaseContainer::iterator	pos,
		std::unique_ptr< base_value_type >	newElem
	)

privateinherited

Handle element assignment.

Parameters

pos	Position in the container to assign.
newElem	The new element to assign.

The container must own its elements. Auxiliary data are copied if appropriate.

◆ assignElement() [2/2]

template<class T , class BASE >

void DataVector< T, BASE >::assignElement	(	typename BaseContainer::iterator	pos,
		value_type	newElem
	)

privateinherited

Handle element assignment.

Parameters

pos	Position in the container to assign.
newElem	The new element to assign.

The old element is freed if this container owns elements. Auxiliary data are copied if appropriate.

◆ at() [1/2]

template<class T , class BASE >

ElementProxy DataVector< T, BASE >::at ( size_type n )

inherited

Access an element, as an lvalue.

Parameters

n	Array index to access.

Returns: Proxy to the element at n.

Will raise std::out_of_range if the index is out-of-bounds. Note that we return a proxy object rather than a reference; the proxy will handle deleting an owned element if it's assigned to.

◆ at() [2/2]

template<class T , class BASE >

const T* DataVector< T, BASE >::at ( size_type n ) const

inherited

Access an element, as an rvalue.

Parameters

n	Array index to access.

◆ auxbase()

template<class T , class BASE >

const SG::AuxVectorBase& DataVector< T, BASE >::auxbase ( ) const

inherited

Convert to AuxVectorBase.

Needed to get AuxVectorBase from a ConstDataVector. Present in DataVector as well for consistency. We only really need it in the base class; however, root6 fails constructing a TMethodCall for this if there is virtual derivation. A workaround is to redeclare this in the derived classes too.

◆ back() [1/2]

template<class T , class BASE >

ElementProxy DataVector< T, BASE >::back ( )

inherited

Access the last element in the collection as an lvalue.

Returns: Proxy to the last element in the collection.

◆ back() [2/2]

template<class T , class BASE >

const T* DataVector< T, BASE >::back ( ) const

inherited

Access the last element in the collection as an rvalue.

Returns: The last element in the collection.

staticinherited

Return the offset of a base DataVector class.

Parameters

ti	`std::type_info` of the desired class.

If ti represents a DataVector base class of this one, then return the offset of that base class. Otherwise, return -1.

This function is here due to limitations of root 6, which can't calculate these offsets correctly from the dictionary if virtual derivation is used.

◆ baseOffset1()

template<class T , class BASE >

static int DataVector< T, BASE >::baseOffset1	(	const char *	p,
		const DataVector< T, BASE > &	dv,

template<class T , class BASE >

const_iterator DataVector< T, BASE >::cend ( ) const

noexceptinherited

Return a const_iterator pointing past the end of the collection.

Returns: A const_iterator.

Note that dereferencing the iterator will yield a const T* rather than a reference.

◆ clear() [1/6]

template<class T , class BASE >

void DataVector< T, BASE >::clear ( )

inherited

virtual const std::type_info& DataVector< T, BASE >::dv_typeid ( ) const

privatevirtualinherited

Find the most-derived DataVector class in the hierarchy.

Returns: The type_info for the class for which this method gets run.

This is used to generate a nice error message when the most-derived check for insertions fails. Every DataVector defines this virtual method, so when it's called, the one corresponding to the most-derived DataVector gets run.

pElem	The element to add to the collection.

Returns: An iterator that points to the inserted data.

The container's ownership policy will determine if it takes ownership of the new element.

Note: this method may only be called using the most derived DataVector in the hierarchy.

For DataVector, this is just the same as insert. It's included just for interface compatibility with std::vector.

◆ emplace_back()

template<class T , class BASE >

value_type DataVector< T, BASE >::emplace_back ( value_type pElem )

inherited

Add an element to the end of the collection.

Parameters

pElem The element to add to the collection.

The container's ownership policy will determine if it takes ownership of the new element.

Note: this method may only be called using the most derived DataVector in the hierarchy.

For DataVector, this is like the same as push_back, and it returns the pushed element. It's included just for interface compatibility with std::vector.

◆ erase() [2/2]

template<class T , class BASE >

iterator DataVector< T, BASE >::erase ( iterator position )

inherited

Remove element at a given position.

Parameters

position Iterator pointing to the element to be removed.

inherited

Access the first element in the collection as an lvalue.

Returns: Proxy to the first element in the collection.

l	An initializer list.

The container's ownership policy will determine if it takes ownership of the new element.

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ insert() [4/5]

template<class T , class BASE >

iterator DataVector< T, BASE >::insert	(	iterator	position,
		std::unique_ptr< base_value_type >	pElem
	)

inherited

Add a new element to the collection.

Parameters

position	Iterator before which the element will be added.
pElem	The element to add to the collection.

Returns: An iterator that points to the inserted data.

The container must be an owning container.

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ insert() [5/5]

template<class T , class BASE >

iterator DataVector< T, BASE >::insert	(	iterator	position,
		value_type	pElem
	)

inherited

Add a new element to the collection.

Parameters

position	Iterator before which the element will be added.
pElem	The element to add to the collection.

Returns: An iterator that points to the inserted data.

The container's ownership policy will determine if it takes ownership of the new element.

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ insertMove()

template<class T , class BASE >

void DataVector< T, BASE >::insertMove	(	iterator	position,
		DataVector< T, BASE > &	other
	)

inherited

Insert the contents of another DataVector, with auxiliary data copied via move semantics.

Parameters

position	Iterator before which the new elements will be added.
other	The vector to add.

The ownership mode of this vector must be the same as other; otherwise, an exception will be thrown.

If both vectors are view vectors, then this is the same as insert (position, other.begin(), other.end()) .

Otherwise, the elements from other will be inserted into this vector. This vector will take ownership of the elements, and the ownership mode of other will be changed to VIEW_ELEMENTS. Auxiliary data for these elements will be transferred, using move semantics if possible. (Thus, the auxiliary store for other may be modified and must not be locked.) Finally, the auxiliary store pointer for other will be cleared (but the store itself will not be deleted since it's not owned by the vector).

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ iter_swap()

template<class T , class BASE >

static void DataVector< T, BASE >::iter_swap	(	iterator	a,
		iterator	b
	)

staticinherited

Swap the referents of two DataVector iterators.

Parameters

ElementProxy DataVector< T, BASE >::operator[] ( size_type n )

inherited

Access an element, as an lvalue.

Parameters

n	Array index to access.

Returns: Proxy to the element at n.

No bounds checking is done. Note that we return a proxy object rather than a reference; the proxy will handle deleting an owned element if it's assigned to.

◆ operator[]() [2/2]

template<class T , class BASE >

const T* DataVector< T, BASE >::operator[] ( size_type n ) const

inherited

Access an element, as an rvalue.

template<class T , class BASE >

void DataVector< T, BASE >::pop_back ( )

inherited

◆ push_back() [1/2]

template<class T , class BASE >

value_type DataVector< T, BASE >::push_back ( std::unique_ptr< base_value_type > pElem )

The container's ownership policy will determine if it takes ownership of the new element.

Note: this method may only be called using the most derived DataVector in the hierarchy.

Returns the pushed pointer.

◆ rbegin() [1/2]

template<class T , class BASE >

const_reverse_iterator DataVector< T, BASE >::rbegin ( ) const

noexceptinherited

Return a const_reverse_iterator pointing past the end of the collection.

Returns: A const_reverse_iterator.

Note that dereferencing the iterator will yield a const T* rather than a reference.

◆ rbegin() [2/2]

template<class T , class BASE >

reverse_iterator DataVector< T, BASE >::rbegin ( )

noexceptinherited

Return a reverse_iterator pointing past the end of the collection.

Returns: A reverse_iterator.

Note that dereferencing the iterator will yield a proxy rather than a reference; the proxy will handle deleting an owned element if it's assigned to.

template<class T , class BASE >

reverse_iterator DataVector< T, BASE >::rend ( )

noexceptinherited

Return a reverse_iterator pointing at the beginning of the collection.

Returns: A reverse_iterator.

Note that dereferencing the iterator will yield a proxy rather than a reference; the proxy will handle deleting an owned element if it's assigned to.

◆ reserve()

template<class T , class BASE >

void DataVector< T, BASE >::reserve ( size_type n )

inherited

Attempt to preallocate enough memory for a specified number of elements.

Parameters

n	Number of elements required.

◆ resize() [1/2]

template<class T , class BASE >

void DataVector< T, BASE >::resize ( size_type sz )

inherited

Resizes the collection to the specified number of elements.

Parameters

sz	The new size of the collection.

Note that this function differs from the standard in that it does not allow specifying the value of any inserted elements. They will always be 0.

If the container is shrunk, elements will be deleted as with erase().

◆ resize() [2/2]

template<class T , class BASE >

void DataVector< T, BASE >::resize ( size_type sz )

inherited

◆ resortAux()

template<class T , class BASE >

void DataVector< T, BASE >::resortAux	(	iterator	beg,
		iterator	end
	)

inherited

Reset indices / reorder aux data after elements have been permuted.

Parameters

beg	Start of the range of elements to process.
end	End of the range of elements to process.

Call this after some operation that has permuted the elements in the container (such as sort). The index information in the elements will be used to permute all auxiliary data in the same way. Finally, all the indices will be reset in the correct order.

◆ setMostDerived()

template<class T , class BASE >

virtual void DataVector< T, BASE >::setMostDerived ( )

protectedvirtualinherited

Set m_isMostDerived for this instance and clear it for all bases.

Called from testInsert if the test fails. The flag may not have been set if this container was made via copy construction, so set it appropriately now so we can test again.

◆ shift()

template<class T , class BASE >

void DataVector< T, BASE >::shift	(	size_t	pos,
		ptrdiff_t	offs
	)

privateinherited

Shift the auxiliary elements of the container.

Parameters

pos	The starting index for the shift.
offs	The (signed) amount of the shift.

The elements in the container should have already been shifted; this operation will then adjust the element indices and also shift the elements in the vectors for all aux data items. offs may be either positive or negative.

If offs is positive, then the container is growing. The container size should be increased by offs, the element at pos moved to pos + offs, and similarly for following elements. The elements between pos and pos + offs should be default-initialized.

If offs is negative, then the container is shrinking. The element at pos should be moved to pos + offs, and similarly for following elements. The container should then be shrunk by -offs elements (running destructors as appropriate).

◆ shrink_to_fit()

template<class T , class BASE >

void DataVector< T, BASE >::shrink_to_fit ( )

inherited

◆ size()

template<class T , class BASE >

size_type DataVector< T, BASE >::size ( ) const

noexceptinherited

Returns the number of elements in the collection.

Could in principle be inherited from the base class, but redeclared in the derived class to avoid root6 bugs.

◆ sort() [1/2]

template<class T , class BASE >

void DataVector< T, BASE >::sort ( )

inherited

Sort the container.

This just sorts by pointer value, so it's probably not very useful.

◆ sort() [2/2]

template<class T , class BASE >

template<class COMPARE >

void DataVector< T, BASE >::sort ( COMPARE comp )

inherited

Sort the container with a user-specified comparison operator.

Parameters

comp	Functional to compare two values.

◆ stdcont()

template<class T , class BASE >

const PtrVector & DataVector< T, BASE >::stdcont ( ) const

inherited

Return the underlying std::vector of the container.

Returns: Reference to the std::vector actually holding the collection.

Note that DataVector<T>::stdcont does not necessarily return a std::vector<T*> if DataVector inheritance is being used.

◆ swap()

template<class T , class BASE >

void DataVector< T, BASE >::swap ( DataVector< T, BASE > & rhs )

inherited

Swap this collection with another.

Parameters

rhs	The collection with which to swap.

Ownership is swapped along with the collection content.

Note: this method may only be called using the most-derived DataVector in the hierarchy. The rhs must also be referenced using the most-derived DataVector.

◆ swapElement() [1/4]

template<class T , class BASE >

void DataVector< T, BASE >::swapElement	(	iterator	pos,
		std::unique_ptr< base_value_type >	newElem,
		std::unique_ptr< base_value_type > &	oldElem
	)

inherited

Swap one element out of the container.

Parameters

pos	The element in the container to swap.
newElem	New element to put in the container. May be 0.
oldElem	Reference to receive the element removed from the container.

Reference oldElem is initialized with element pos of the collection (no bounds checking). Then element index is set to newElem.

The collection must own its elements to use its interface. The collection will take ownership of newElem and will return ownership of oldElem.

Note: this method may only be called using the most derived DataList in the hierarchy.

◆ swapElement() [2/4]

template<class T , class BASE >

void DataVector< T, BASE >::swapElement	(	iterator	pos,
		value_type	newElem,
		reference	oldElem
	)

inherited

Swap one element out of the container.

Parameters

pos	The element in the container to swap.
newElem	New element to put in the container. May be 0.
oldElem	Reference to receive the element removed from the container.

Reference oldElem is initialized with element pos of the collection (no bounds checking). Then element index is set to newElem. If the collection owns its elements, then it will take ownership of newElem and release (without deleting) the element returned through oldElem.

Note: this method may only be called using the most derived DataList in the hierarchy.

◆ swapElement() [3/4]

template<class T , class BASE >

void DataVector< T, BASE >::swapElement	(	size_type	index,
		std::unique_ptr< base_value_type >	newElem,
		std::unique_ptr< base_value_type > &	oldElem
	)

inherited

Swap one element out of the container.

Parameters

index	Index of the element in the container to swap.
newElem	New element to put in the container. May be 0.
oldElem	Reference to receive the element removed from the container.

Reference oldElem is initialized with element index of the collection (no bounds checking). Then element index is set to newElem.

The collection must own its elements to use its interface. The collection will take ownership of newElem and will return ownership of oldElem.

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ swapElement() [4/4]

template<class T , class BASE >

void DataVector< T, BASE >::swapElement	(	size_type	index,
		value_type	newElem,
		reference	oldElem
	)

inherited

Swap one element out of the container.

Parameters

index	Index of the element in the container to swap.
newElem	New element to put in the container. May be 0.
oldElem	Reference to receive the element removed from the container.

Reference oldElem is initialized with element index of the collection (no bounds checking). Then element index is set to newElem. If the collection owns its elements, then it will take ownership of newElem and release (without deleting) the element returned through oldElem.

Note: this method may only be called using the most derived DataVector in the hierarchy.

◆ testInsert()

template<class T , class BASE >

void DataVector< T, BASE >::testInsert ( const char * op )

inherited

Test if we can insert; raise an exception if not.

Parameters

op	Description of the attempted operation.

In order to maintain type-safety, we can only allow insertions using the most-derived instance of DataVector. This checks this by testing the m_isMostDerived, which is set by the constructors to true only for the most-derived instance. If the test fails, we call to potentially out-of-line code to continue.

◆ testInsertOol()

template<class T , class BASE >

void DataVector< T, BASE >::testInsertOol ( const char * op )

inherited

Test if we can insert; raise an exception if not.

Parameters

op	Description of the attempted operation.

This continues the test of testInsert. There is one case where m_isMostDerived may not be set correctly. If this container was made via copy construction, then all the m_isMostDerived flags will be false. So we call setMostDerived to set the flags correctly and test again. If the test fails again, then we raise an exception.
