Interface Entity<I extends Serializable>

Show UML class diagram

Type Parameters:

I - The id property class

All Known Subinterfaces:

OptLockEntity<I>

All Known Implementing Classes:

EntityImpl

public interface Entity<I extends Serializable>

This interface should be implemented by all entity objects.

An entity is an object whose identity does not come from its attributes but from an independent identification schema

In our case the identification schema is a particular property called "id" whose class is a generic parameter of this interface.

The id property is the identifier for objects that implements this interface so equals and hashCode methods must be implemented so to use this property to accomplish their job

For details on entity objects see Eric Evans, Domain Driven Design [Addison Wesley] Ch. 4
