Detailed Description

Container for Jets

JetCollection is a DataVector of Jets. It is the main data object and acts as a central point for all jet related software.
It holds a JetMomentMap and JetKeyDescriptorInstance which it serves to the jets it holds.

It redefines the push_back and insert method in order to

let the jets know they are owned by a JetCollection
perform the related operations (moment map)

It also defines an order enum (OrderedVar), and holds the order status
of the collection (ByEtDown, ByEtUp,etc..)

IMPORTANT* : one should not record this object by using StoreGate::record(), but rather use the JetCollectionHelper::record(). The reason is this function performs all the necessary operations needed to deal with the JetMomentMap.

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]

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

inherited

Access an element, as an rvalue.

Parameters

n	Array index to access.

 }

◆ auxbase()

const SG::AuxVectorBase& DataVector< Jet , BASE >::auxbase

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]

ElementProxy DataVector< Jet , BASE >::back

inherited

Access the last element in the collection as an lvalue.

Returns: Proxy to the last element in the collection.

No checking is done to ensure that the container is not empty. Note that we return a proxy object rather than a reference; the proxy will handle deleting an owned element if it's assigned to.

◆ back() [2/2]

const Jet * DataVector< Jet , BASE >::back

inherited

Access the last element in the collection as an rvalue.

Returns: The last element in the collection.

No checking is done to ensure that the container is not empty. Note that we return a const T* rather than a reference.

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.

void DataVector< Jet , BASE >::clear ( std::unique_ptr< Deleter > deleter )

inherited

Erase all the elements in the collection, and change how elements are to be deleted.

Parameters

virtual const std::type_info& DataVector< Jet , BASE >::dv_typeid

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.

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.

		std::initializer_list< value_type >	l
	)

inherited

Add a group of new elements to the collection.

Parameters

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() [5/6]

iterator DataVector< Jet , 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() [6/6]

		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()

void DataVector< Jet , BASE >::insertMove	(	iterator	position,
		DataVector< Jet > &	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.

inherited

Resizes the collection to the specified number of elements.

Parameters

sz	The new size of the collection.

◆ setMostDerived()

virtual void DataVector< Jet , BASE >::setMostDerived

protectedvirtualinherited

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

		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()

inherited

Sort the container with a user-specified comparison operator.

Parameters

comp	Functional to compare two values.

◆ stdcont()

const PtrVector & DataVector< Jet , BASE >::stdcont

inherited

Return the underlying std::vector of the container.

◆ swap()

void DataVector< Jet , BASE >::swap ( DataVector< Jet > & 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]

void DataVector< Jet , 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]

void DataVector< Jet , 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]

void DataVector< Jet , 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]

void DataVector< Jet , 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()

void DataVector< Jet , 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()

void DataVector< Jet , 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.
