Syntax
public interface IEbicsContactFolder : ICollection, IEnumerable
Remarks

The EbicsContact class provides the capability of maintaining itself through any IEbicsContactFolder implementation which is provided by the application. Thus an application can completely control the storage of contact data. For simple applications a default implementation EbicsContactFolder is provided that stores the contacts as individual XML files in the file system.

The content of a IEbicsContactFolder must be enumerable through its base interface IEnumerable. There is no guarantee that every enumeration returns the contacts in the same order.

An implementation of IEbicsContactFolder must use the various persistency methods of the EbicsContact class in order to serialise and deserialise the object data for storage. No assumptions about the serialised data must be made.
