The aim of this example is to demonstrate the basic object navigation using the POOL Ref< T > class as embedded objects in a persistent class.
The user creates a class library which contains the implementation of a
Hit class, which is associated to a Digit class via an embedded
Ref< Digit > data member, runs the LCG dictionary for these classes and
builds the corresponding dictionary run time library.
A simple writer
application writes Hits and Digits in different containers of a
database file which are specified in the program. Hits and Digits are
written using ROOT Key and ROOT Tree technology respectively. The reader starts
an iteration in the implicit collection of Hit objects defined by the
database/container specified in the writer and prints the contents of each Hit
together with the contents of its associated Digit.
The writer and reader
applications are linked against the user class library. The dictionary library
is explicitly loaded during run time.
