I'm curious as to what the proper way is to denote the signature for
an object that has a timestamp value.
Say I have the following table:
Products {
int productID; <--Primary Key
string productName;
byte[] timeStamp;
}
Would the domain signature / Gethashcode function only implement the
hashcode on the productID, or in the case of this example should it
always also include the timestamp value as well such that the
GetHashCode comparison may look like this:
public override int GetHashCode()
{
System.Text.StringBuilder sb = new
System.Text.StringBuilder();
sb.Append(this.GetType().FullName);
sb.Append(productID);
sb.Append(timeStamp);
return sb.ToString().GetHashCode();
}
What is the correct way? If you searching for uniqueness in a domain
object I would think you would always want to include the timestamp
value, am I wrong in my interpretation?
