GetterSetter

Getters and Setters in Piriti

Getters / Setters

When mapping data from JSON / XML to POJOs Piriti tries to assign the mapped values to the annotated fields. If the fields are not accessible Piriti tries to use default getters / setter methods. Sometimes you want to have private fields and no setter. In order to still map the data you can use custom getters / setters. Suppose you have the following POJO: public class Project { private String name; private List members;

    public Project()
    {
        this.members = new ArrayList<User>();
    }


    public String getName()
    {
        return name;
    }


    public void setName(String name)
    {
        this.name = name;
    }


    public List<User> getMembers()
    {
        return members;
    }
    
    
    public void clearMembers()
    {
        members.clear();
    }


    public void addMember(User user)
    {
        members.add(user);
    }
}

There's no way to set the members directly. In this case you can implement a custom setter:

public class ProjectMembersSetter implements PropertySetter<Project, List<User>>
{
    @Override
    public void set(Project model, List<User> value)
    {
        model.clearMembers();
        if (value != null)
        {
            for (User user : value)
            {
                model.addMember(user);
            }
        }
    }
}

and use it in the mappping for members:

public class Project
{
    ...
    @Setter(ProjectMembersSetter.class) 
    private List<User> members;
    ...
}
