Detailed Description

template<class STORED, class CONTAINER>
class HolderImp< STORED, CONTAINER >

This is an implementation class for all Holders It is templated with 2 arguments STORED which is type of stored objects Another type is CONTAINER for that type.

Examples when it works are: HolderImp<A, DataVector > — typical HolderImp< A, Acontainer> > — as above, Acontainer is either typedef for DataVector or inherits from it HolderImp< DataVector, DataVector > — when both are of the same type HolderImp< Acontainer, Acontainer> > — as above

deserializeDynVars() [2/2]

serializeDynVars()

bool IHolder::serializeDynVars ( const SG::IAuxStoreIO & iio, const xAOD::AuxSelection & sel, std::vector< uint32_t > & dataBlob )

Serialize all selected dynamic variables for an xAOD object.

Parameters

	iio	The auxiliary store for the xAOD object.
	sel	Selection object for variables to write.
[out]	dataBlob	Serialized data.

Returns true on success, false on failure.

Each selected dynamic variable is concatenated to dataBlob as follows.

• Length serialized name data (1 word).
• Serialized name data.
• Length of serialized type name (1 word).
• Serialized type name data.
• Length of serialized variable data (1 word).
• Serialized data for the variable, as produced by TrigTSerializer.
