java.lang.Object
io.github.mahmoudimus.quic.tls.ClientSessionMemoryCache
All Implemented Interfaces:
ClientSessionStore
public final class ClientSessionMemoryCache extends Object implements ClientSessionStore
A bounded, in-memory ClientSessionStore: up to a number of servers, each with up to 8 tickets. A full cache forgets the server added first; a full server entry forgets its oldest ticket. Tickets are taken newest first, and only once.

Thread-safe: a ReentrantLock guards the map.
