45 * @interface ICollection
46 * @brief This interface represents a collection of objects.
47 * It defines the size, enumerators, and the synchronization mechanism of a collection.
51 * The %ICollection interface represents a collection of objects. It defines the size, enumerators, and the synchronization mechanism of a collection.

58 * This polymorphic destructor should be overridden if required. @n
59 * This way, the destructors of the derived classes are called when the destructor of this interface is called.

66 * Gets the number of objects currently stored in the collection.
70 * @return An integer value indicating the number of objects currently stored in the collection
72 virtual int GetCount(void) const = 0;
75 * Gets the enumerator of the %ICollection derived class,
76 * or returns @c null if some exception occurs.
80 * @return A pointer to an enumerator interface of the %ICollection derived class, @n
81 * else @c null if an exception occurs
82 * @exception E_SUCCESS The method is successful.
83 * @exception E_OUT_OF_MEMORY The memory is insufficient.
84 * @remarks Use this method to obtain an enumerator (an instance of the IEnumerator derived class)
85 * to iterate over a collection (an instance of the %ICollection derived class).
86 * @remarks The specific error code can be accessed using GetLastResult() method.
