virtual std::string typeName() const =0
VariableContainer()
Default constructor.
int NumRequests(const FactoryBase *reqFactory) const
Return the number of times the data has been requested by a specific factory.
void AddKeepFlag(KeepType keep=UserData)
Adds a keep flag to the flag combination.
static T & get(DataBase *data_, DataBase *&)

KeepType GetKeepFlag() const
Returns the keep flag combination.
void SetData(const T &entry)
Store data in container class and set the "Available" status true.
User data are always kept. This flag is set automatically when Level::Set("data", data) is used...
bool IsRequested() const
Returns true, if data is requested by at least one factory.
void RemoveKeepFlag(KeepType keep=UserData)
Removes a keep flag to the flag combination.
