fs28 Class Description

fs28 The NSMutableDictionary class declares the programmatic interface to objects that manage mutable associations of keys and values. With its two efficient primitive methods'd0b setObject:forKey:b0 and b removeObject:forKey:b0 'd0this class adds modification operations to the basic operations it inherits from NSDictionary.
fs16
fs28 The other methods declared here operate by invoking one or both of these primitives. The derived methods provide convenient ways of adding or removing multiple entries at a time.
fs16
fs28 When an entry is removed from a mutable dictionary, the key and value objects that make up the entry receive ab releaseb0 message, which can cause them to be deallocated. Note that if your program keeps a reference to such objects, the reference will become invalid unless you remember to send the object a b retainb0 message before it'27s removed from the dictionary. For example, the third statement below could result in a run-time error, except for the b retainb0 message in the first statement:

[i aDictionaryi0 removeObjectForKey:i theKeyi0 ];
