// GTMLightweightProxy
//
// An object which does nothing but stand in for another object and forward
// messages (other than basic NSObject messages) to it, suitable for breaking
// retain cycles. It does *not* retain the represented object, so the
// represented object must be set to nil when that object is deallocated.
//
// Messages sent to a GTMLightweightProxy with no represented object set will
// be silently discarded.
//
@interface GTMLightweightProxy : NSProxy {
@private
GTM_WEAK id representedObject_;
}
// Initializes the object to represent |object|.
- (id)initWithRepresentedObject:(id)object;
// Gets the object that the proxy represents.
- (id)representedObject;
// Changes the proxy to represent |object|
