Dozer, how to map using methods result

Dozer, how to map using methods result

Have for exemple two classes :
public class A
{
public int doSomething()
{
return 12;
}
}
public class B
{
private int something;
public int getSomething()
{
return something;
}
public void setSomething(int s)
{
something = s;
}
}
Can I map the result of doSomething() in A to something in B ?
Thanks for your answers :)
