Member Enumeration Documentation

AuxStoreType

enum SG::IAuxStoreHolder::AuxStoreType

inherited

Type of the auxiliary store.

In the xAOD EDM we use auxiliary store objects in some cases to describe a single object, and in most cases to describe a container of objects. This enumeration declares which type the object implementing this interface is.

Enumerator
AST_ObjectStore	The store describes a single object.
AST_ContainerStore	The store describes a container.

Definition at line 66 of file IAuxStoreHolder.h.

                        {
         AST_ObjectStore    = 0,

insertMove() [2/2]

virtual bool SG::IAuxStore::insertMove ( size_t  pos, IAuxStore &  other, const SG::auxid_set_t &  ignore = SG::auxid_set_t()  )

pure virtualinherited

Move all elements from other to this store.

Parameters

pos	The starting index of the insertion.
other	Store from which to do the move.
ignore	Set of variables that should not be added to the store.

Let len be the size of other. The store will be increased in size by len elements, with the elements at pos being copied to pos+len. Then, for each auxiliary variable, the entire contents of that variable for other will be moved to this store at index pos. This will be done via move semantics if possible; otherwise, it will be done with a copy. Variables present in this store but not in other will have the corresponding elements default-initialized. Variables in other but not in this store will be added unless they are in ignore.

Returns true if it is known that none of the vectors' memory moved, false otherwise.

Implemented in SG::AuxStoreInternal.

Mark that this type supports thinning operations.

See AthContainers/supportsThinning.h and AthenaPoolCnvSvc/T_AthenaPoolCnv.h. Helps guide which pool converter template will be used. If false, the default pool converter will be used rather than the aux store-specific one. Ordinary xAOD type should not touch this, but may be overridden in a derived class to handle certain special cases.
