encapsulation

I have a User entity: use Doctrine\ORM\Mapping as ORM; /** * ExampleBundle\Entity\User * * @ORM\Entity() */ class User { // ... /** * @ORM\Column(type="service_expires_at", type="date", nullable=true) */ private $service_expires_at; public function getServiceExpiresAt() { return $this->service_expires_at; } public function setServiceExpiresAt(\DateTime $service_expires_at) { $this->service_expires_at = $service_expires_at; } } When i update the User's service_expires_at as following, the updated service_expires_at value is NOT saved back into the database: $date = $user->getServiceExpiresAt();

I want to hide public methods from the intellisense member list. I have created an attribute that when applied to a method will cause the method to be called when its object is constructed. I've done this to better support partial classes. The problem is that in some environments (such as Silverlight), reflection cannot access private members even those of child classes. This is a problem since all of the work is done in a base class. I have to make these methods public, but I want them to be hidden from intellisense, similar to how the Obsolete attribute works. Frankly, because I am anal

This is basic question but still i don't understand encapsulation concept . I did't understand how can we change the properties of class from other class.because whenever we try to set the public instance value of class we have to create object of that class and then set the value.and every object refer to different memory.so even if we change the instance value this will not impact to any other object. Even I try to change using static public instance value also i am not able to change the class property value. Example is given below // Employee class public class Employee { public static int

I have spent quite a few hours pondering the subject of exposing list members. In a similar question to mine, John Skeet gave an excellent answer. Please feel free to have a look. ReadOnlyCollection or IEnumerable for exposing member collections? I am usually quite paranoid to exposing lists, especially if you are developing an API. I have always used IEnumerable for exposing lists, as it is quite safe, and it gives that much flexibility. Let me use an example here public class Activity { private readonly IList<WorkItem> workItems = new List<WorkItem>(); public string Name { get; set; } public
