NestedAttribute API Document

Maps properties of a child object to columns of the table of a parent class.

Example

The following code illustrates the use of a nested PostalAddress

class

    [ActiveRecord("Companies")]
    public class Company : ActiveRecordBase
    {
        private int id;
        private PostalAddress _address;
    
        public Company()
        {
        }
    
        public Company(string name)
        {
            this.name = name;
        }
    
        [PrimaryKey]
        private int Id
        {
            get { return id; }
            set { id = value; }
        }
    
        [Nested]
        public PostalAddress Address
        {
            get { return _address; }
            set { _address = value; }
        }
    }
    
    public class PostalAddress
    {
        private String _address;
        private String _city;
        private String _state;
        private String _zipcode;
    
        [Property]
        public String Address
        {
            get { return _address; }
            set { _address = value; }
        }
    
        [Property]
        public String City
        {
            get { return _city; }
            set { _city = value;}
        }
    
        [Property]
        public String State
        {
            get { return _state; }
            set { _state = value; }
        }
    
        [Property]
        public String ZipCode
        {
            get { return _zipcode; }
