Re: [Hibernate] CodeGenerator

[Juozas B. <ba...@ce...>]

equals() and hashCode() can be implemented using this definition :

for all persistent objects a, b :
 a.equals(a)       ===     true 
 a.equals(b)       ==>     b.equals(a)  
 a.equals(b)       ==>     a.hashCode() = b.hashCode()    
 a is persistent   ==>     a.getId() != null
 a.equals(b)       <=>    a.getId().equals(b.getId())  
 a is persistent   ==>    a.hashCode() = a.getId().hashCode()
