Hi,
Am an learning Erick’s DDD book, i really feel the greatness of it. I just started of reading the book and ending up with lot of questions.
In the 2nd chapter : He defines the Layered super type model and has given a sample entity base class. I can understand this class and its usage except some methods in it.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Since .Net itself provides mechanism to perform the equality tests like (obj1==obj2 , object.Equals(ob1,ob2)) ,
1. what is the special need in the layered super type base class to include and override the following method .
bool Equal(object entity)
public override int GetHashCode()
2. What is the need to introduce the operator overloading in this base class
public static bool operator ==(Entitybase base1, Entitybase base2)
public static bool operator !=(Entitybase base1, Entitybase base2)
Please help me understanding these methods
