Usability

Given a Person class handler implementation:

public class PersonClassHandler : IClassHandler<Person>
{
    public Person Get(Person entity, ClassHandlerGetOptions options)
    {
        return entity;
    }

    public Person Set(Person entity, ClassHandlerSetOptions options)
    {
        return entity;
    }
}

How to Map?

A class handler can be mapped to an entity model using any of the following approaches.

Via ClassHandlerMapper:

PropertyHandlerMapper
    .Add(typeof(Person), new PersonClassHandler(), true);

Via FluentMapper:

FluentMapper
    .Entity<Person>()
    .ClassHandler<PersonClassHandler>();

Via the ClassHandler attribute:

[ClassHandler(typeof(PersonClassHandler))]
publi class Person
{
    ...
}
