Detailed Description

An abstract class for storing objects in a dictionary.

Keys are copied and thus must conform to the OFCopying protocol.

Note
Fast enumeration on a dictionary enumerates through the keys of the dictionary.
Subclasses must implement objectForKey: (OFDictionary), count and keyEnumerator (OFDictionary).
