class ExpiringMap<K : Any!, V : Any!> : MutableMap<K, V> (source)
A concurrent hash map that stores values along with an expiry. Values are stored in the map until their expiry is reached, after which they will no longer be available and will appear as if removed. The actual removal is done lazily whenever the map is accessed, or when the #purgeExpired() method is invoked.

Force immediate expiration of any key/value pairs that have reached their expiry. fun purgeExpired(): Long |
put |
fun put(key: K, value: V): V?
Associates the specified value with the specified key in this map, and expires the entry when the specified expiry time is reached. If the map previously contained a mapping for the key, the old value is replaced by the specified value. fun put(key: K, value: V, expiry: Long): V?fun put(key: K, value: V, expiry: Long, expiryListener: BiConsumer<K, V>?): V? |

fun putIfAbsent(key: K, value: V): V?
If the specified key is not already associated with a value, associates the specified value with the specified key in this map, and expires the entry when the specified expiry time is reached. fun putIfAbsent(key: K, value: V, expiry: Long): V?fun putIfAbsent(key: K, value: V, expiry: Long, expiryListener: BiConsumer<K, V>?): V? |
