Validations

Add support for validating entities before a save operation occurs. If an entity fails to validate, the save should fail.

Here's the approach to running validations:

• By default, executing a save on an entity will run its validations.
• Validations are executed through the beforeSave callback.
• If the entity has any errors, it will cause its save operation to fault.
• If any entity within a group of entities is invalid, it will cause the whole group to fail.

Defining Validations:

public class User extends Entity
{
    public static const validate:Object = {
        name: [{validator: Length, minimum: 0, message: "Name is too short"}],
        email: [{validator: Email}]
    }
    
    public function User()
    {
        
    }
}
