// QBrowser is a general purpose class for browsing Bonjour services.
// The class is run loop based and must be called from a single thread.
// Specifically, the -start and -stop methods add and remove run loop sources
// to the current thread's run loop, and it's that thread that calls the
// delegate callbacks.
@interface QBrowser : NSObject
- (id)initWithDomain:(NSString *)domain type:(NSString *)type;
// type must not be nil
// domain of nil implies domain of @"" implies browse in default domains
// properties set by the init method

@property (nonatomic, copy, readonly ) NSString * type;
// properties that can be set any time
@property (nonatomic, assign, readwrite) id<QBrowserDelegate> delegate;
// properties that are set as the browser executes
@property (nonatomic, copy, readonly ) NSSet * services; // observable, of NSNetService

// run loop modes
// IMPORTANT: You can't add or remove run loop modes while the browser is running.
