I have a Student class like this
class Student{
private int id;
private String name;
private IBranch branch;
}

and corresponding table in database is

Table Student{
ID int,
Name VARCHAR,
BranchType int
}
IBranch is an interface and classes CSBranch, ECEBranch, ChemicalBranch implements IBranch
Based on branchtype stored as int in database, a branch is created. How to map branchtype from database to branh interface in student object using hibernate
configuration file or branch class is to be created by calling some method.
