What is the closest implementation of Objective-C's NSDictionary
in Java? To me, it looks like HashMap<String, Object>
, but I'm very new to Objective-C.
Thanks
NSDictionary
is a class cluster (see the "Class Cluster" section in The Cocoa Fundamentals Guide), meaning that the actual implementation is hidden from you, the API user. In fact, the Foundation framework will choose the appropriate implementation at run time based on amount of data etc. In addition, NSDictionary
can take any id
as a key, not just NSString
(of course, the -hash
of the key object must be constant).
Thus, closest analog is probably Map<Object,Object>
.
