Class TokenMemoryCache

java.lang.Object
io.github.mahmoudimus.quic.token.TokenMemoryCache
All Implemented Interfaces:
TokenStore
public final class TokenMemoryCache extends Object implements TokenStore
A bounded, in-memory TokenStore: up to a number of server names, each with a queue of up to a number of tokens. Storing a token for a full queue drops its oldest; storing one for a new name when the cache is full evicts the least recently used name. Tokens are taken oldest first.

Thread-safe: a ReentrantLock guards the map.
