Abstract Value Members
- abstract def estimatedSize: Long
Returns the estimated size provided by the underlying cache, -1 if not available.
- abstract def estimatedWeight: Long
Returns the estimated weight provided by the underlying cache, -1 if not available.
- abstract def evictionCount: Long
Returns the eviction count provided by the underlying cache, -1 if not available.
- abstract def evictionWeight: Long
Returns the eviction weight provided by the underlying cache, -1 if not available.
- abstract def get(key: K): V
Returns the value associated to a key.
Returns the value associated to a key.
It returns null if the key is not present in the cache.
- abstract def getAll(keys: Iterable[_ <: K]): Map[K, V]
Returns the values associated to the keys.
Returns the values associated to the keys.
It returns only the entries that are already present in the cache.
- abstract def put(key: K, value: V): Unit
Associates a value with the provided key.
