Parameters
ttlnumber The TTL for all entries added to this mapevictIntervalnumber? How frequently to delete expired entries from the internal mapintialValuesIterable<[K, V]>? An iterable such as an array or another map containing the initial values to set in the map
Returns void
Removes all key/value pairs from the Map object.
Returns void
Removes any value associated with that key
Parameters
keyK the key to delete
Returns boolean
Returns Iterator<[K, V]> a new iterator object that contains an array of [key, value] for each element in the map that has not expired
Calls fn once for each non-expired key-value pair in the map object
Parameters
fnfunction (value: V, index: K, map: any): any the function to callthisArgany the value of this when fn is called
Returns void
Parameters
keyK
Returns V? the value associated with the key, or undefined if there is none or that entry has expired
Parameters
keyK
Returns boolean indicates if the key has an associated value which hasn't expired
Returns Iterator<K> a new iterator containing the keys of each non-expired entry in the map
Sets the value in the map, with a ttl of Date.now() + map.ttl
Parameters
keyKvalueV
Returns any the map
The number of non-expired key/value pairs in the map
Returns number
