Detailed Description

template<class T>
class CdbRooRoIdCollectionR< T >

A persistent collection of 'id'-ed objects.

Classes eligible for this template must have the following minimal interface:

class T { public: T(); T( const T&); UShort_t id() const; };

NOTE: The total number of elements stored in a collection of this type is limited by 64K. Therefore valid indexes of the elements lay in the following range: [0..0xFFFF], inclusive at both sides of the range.

Constructor & Destructor Documentation

template<class T>
CdbRooRoIdCollectionR< T >::CdbRooRoIdCollectionR (    ) 
 

The normal and the default constructor.

It's also needed for ROOT I/O.

Definition at line 25 of file CdbRooRoIdCollectionR.cc.

template<class T>
CdbRooRoIdCollectionR< T >::CdbRooRoIdCollectionR (  const CdbRooRoIdCollectionR< T > &    theOther ) 
 

The copy constructor.

IMPORTANT NOTE:

Watch out for the implementation of this constructor because objects of the class can be in two states: "stored" and "transient". The same object can't be stored more than one time due to a unique naming scheme for persistent collections (and their sub-collections (and their elements)) in ROOT files. The same rule applies to copies of an object - after the master copy got stored then its copies can't be stored anymore.

The cache of objects gets always duplicated since it's using counted smart pointers.

And we don't care about supplementary transient context (other than the transient list of objects). That context is only used to populate the transient list from the persistent store. Copying this context accross objects can be dangerous too.
