Enumeration Type Documentation

AllowEmptyEnum

enum SG::AllowEmptyEnum

Enumerator
AllowEmpty

Definition at line 29 of file StoreGate/StoreGate/VarHandleKey.h.

                    {
  AllowEmpty = 1
};

AuxVarFlags

enum SG::AuxVarFlags

Additional flags to qualify an auxiliary variable.

Enumerator
None	No special flags set.
Atomic	Mark that this variable should only be accessed atomically. If this is set, then the variable can be accessed only via AtomicDecorator. Be aware that this is not completely safe; it is still possible to have non-atomic accesses to the variable via either the implicit operations provided by this class or by explicit access to the value vector. Therefore, this is not recommended for general use. Contact core software before using this for new code.
SkipNameCheck
ATH_BITMASK	Enable bitwise functions on this enum; see bitmask.h.

Definition at line 58 of file AuxTypes.h.

                 {
  None   = 0x00,
 
  Atomic = 0x01,
 
  // These flags control the behavior of findAuxID() but are not
  // stored with the variable.
  SkipNameCheck = 0x80,
 
  ATH_BITMASK
};

IndexTrackingPolicy

enum SG::IndexTrackingPolicy

Enumerator
DEFAULT_TRACK_INDICES	Default value. Set index tracking based on the ownership policy. If this container owns its elements, then track indices; otherwise do not.
ALWAYS_TRACK_INDICES	Always track indices, regardless of the setting of the ownership policy.
NEVER_TRACK_INDICES	Never track indices, regardless of the setting of the ownership policy.

Definition at line 37 of file IndexTrackingPolicy.h.

                         {
  DEFAULT_TRACK_INDICES,
 
  ALWAYS_TRACK_INDICES,
 
  NEVER_TRACK_INDICES
};

OwnershipPolicy

enum SG::OwnershipPolicy

describes the possible element ownership policies (see e.g. DataVector)

copyAuxStoreThinned()

void SG::copyAuxStoreThinned	(	const SG::IConstAuxStore &	orig,
		SG::IAuxStore &	copy,
		const SG::ThinningInfo *	info
	)

Helper to copy an aux store while applying thinning.

Parameters

orig	Source aux store from which to copy.
copy	Destination aux store to which to copy.
info	Thinning information for this object (or nullptr).

orig and copy are both auxiliary store objects. The data from orig will be copied to copy, with individual elements / variables removed according info.

copyThinned()

template<class CONTAINER >

std::unique_ptr<CONTAINER> SG::copyThinned	(	CONTAINER &	orig,
		const SG::ThinningInfo *	info
	)

Helper to copy an object while applying thinning.

Parameters

orig	The object to copy.
info	Thinning information for this object (or nullptr).

Returns a new copy of orig with elements removed according to the thinning defined in svc. Ownership of the new object is passed back to the caller.

The code here handles IAuxStore objects. (For a DataVector object, use copyThinnedConst.) Support for additional object types may be added by adding overloads for copyThinned1.

	)

Helper to copy an object while applying thinning.

Parameters

orig	The object to copy.
dummy	Dummy argument for overload resolution.
info	Thinning information for this object (or nullptr).

This overload handles DataVector types. It returns a view container copy of orig, from which any thinned elements are removed.

	)

Helper to copy an object while applying thinning.

Parameters

orig	The object to copy.
dummy	Dummy argument for overload resolution.
info	Thinning information for this object (or nullptr).

This is the generic version of copyThinned, which matches types for which there is not a more specific overload. It simply makes a copy of orig using the copy constructor.

key	The decoration name.

Construct the StoreGate key from the associated container and the decoration name passed in key. If the latter also contains the container name, an exception will be raised.

Parameters

contKey	The VarHandleKey of the container holding the decoration.
key	The decoration name.

Construct the StoreGate key from the associated container and the decoration name passed in key. If the latter also contains the container name, an exception will be raised if the name does not match contKey.

makeHandle() [1/18]

template<class D , class T >

ReadDecorHandle<T, D> SG::makeHandle

(

const ReadDecorHandleKey< T > &

key

)

Return a ReadDecorHandle referencing key.

Parameters

key	The key object holding the clid/key/store.

This will raise an exception if the StoreGate key is blank, or if the event store cannot be found.

The type of the decoration must be included as an explicit template parameter:

auto handle = SG::makeHandle<float> (key);

Note that D comes first in the argument list. It's given explicitly, while T is inferred from key.

makeHandle() [2/18]

template<class T >

void SG::makeHandle

(

const ReadDecorHandleKey< T > &

key

)

These two signatures are to catch cases where the explicit template argument is omitted from the makeHandle call and give an error tailored to that.

Otherwise, the makeHandle call for ReadHandle would match, potentially giving a much more confusing error.

makeHandle() [3/18]

template<class D , class T >

ReadDecorHandle<T, D> SG::makeHandle	(	const ReadDecorHandleKey< T > &	key,

Return a ReadDecorHandle referencing key for an explicit context.

Parameters

key	The key object holding the clid/key/store.
ctx	The event context.

This will raise an exception if the StoreGate key is blank, or if the event store cannot be found.

normalizedTypeinfoName()

std::string SG::normalizedTypeinfoName

(

const std::type_info &

info

)

Convert a type_info to a normalized string representation (matching the names used in the root dictionary).

Parameters

info	The type to convert.

The function AthContainer_detail::typeinfoName may be used to convert a C++ type_info to a string representing the name of the class; this handles platform-dependent details such as performing demangling.

However, the name you get as a result of this does not necessarily match the name by which the class is known in the ROOT dictionary. In particular, defaulted template arguments for STL containers and DataVector are suppressed in the dictionary. So, for example, for a vector class typeinfoName may produce std::vector<int, std::allocator<T> >, while in the dictionary it is known as std::vector<int>. Using normalizedTypeinfoName instead will transform the names to match what's in the dictionary. This function will also cache the typeinfo -> string conversions.

Definition at line 120 of file normalizedTypeinfoName.cxx.

{
  // Maintain a cache of mappings, protected with an ordinary mutex.
  // We originally did this with an upgrading mutex.
  // However, these mutexes have been observed to have considerable overhead,
  // so are probably not worthwhile if the read critical section is short.

  // or rcu-style solution.
