TERecord

Clojure inspired records for Objective-C. Fully KVO-compliant.

git submodule init
git submodule update

Step 1: Instead of a class, create a protocol

@protocol Folder <TERecord>
@property (nonatomic, strong) NSString *uuid;
@property (nonatomic, strong) id<Storage> storage;
@property (nonatomic, strong) id<DiskInfo> diskinfo;
@property (nonatomic, strong) NSURL *mountpoint;
@property (nonatomic, strong) NSNumber *autounlock;
@property (nonatomic, strong) NSNumber *encrypted;
@property (nonatomic, strong) NSNumber *autolock;
@property (nonatomic, strong) NSMutableArray *lockActions;
@property (nonatomic, strong) NSMutableArray *unlockActions;
@end

Step 2: Call TERecordCreate to create instances

id<Folder> TEFolderCreate(id<Storage> storage, NSURL *mountpoint)
{
    id<Folder> f = TERecordCreate(@protocol(Folder));
    f.uuid = [NSString UUID];
    f.storage = storage;
    f.mountpoint = mountpoint;
    f.autolock = @0;
    f.autounlock = @NO;
    f.encrypted = @NO;
    f.unlockActions = [[NSMutableArray alloc] init];
    f.lockActions = [[NSMutableArray alloc] init];
    return f;
}

Step 3: There is no step 3!

That's it! You can now use these instances just as you would regular instances of Objective-C classes, except there's no need to create any accessors for them! They can even be serialized to disk and loaded back!

Updating serialized records with new properties from the protocol

Simply call TERecordUpdateProtocol on the instance, like so:

TERecordUpdateProtocol(folder, @protocol(Folder));
