19// KSMemoryTicketStore
20//
21// This KSTicketStore subclass represents an in-memory, temporary ticket store
22// that does not persist across invocations of the application. The tickets
23// stored in this store are only stored as long as the KSMemoryTicketStore
24// instance exists. This is simply a KSTicketStore that is backed by an
25// in-memory NSDictionary rather than disk. The arg passed to -initWithPath:
26// MUST be nil.
27//
28// Sample usage:
29//
30//   KSTicket *t = ...
31//   KSTicketStore *ts = [[KSMemoryTicketStore alloc] init];
32//   [ts storeTicket:t];        // [ts ticketCount] == 1
33//   [ts storeDeleteTicket:t];  // [ts ticketCount] == 0
34//
