Abstract Value Members

  1. abstract def estimatedSize: Long

    Returns the estimated size provided by the underlying cache, -1 if not available.

  2. abstract def estimatedWeight: Long

    Returns the estimated weight provided by the underlying cache, -1 if not available.

  3. abstract def evictionCount: Long

    Returns the eviction count provided by the underlying cache, -1 if not available.

  4. abstract def evictionWeight: Long

    Returns the eviction weight provided by the underlying cache, -1 if not available.

  5. 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.

  6. 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.

  7. abstract def put(key: K, value: V): Unit

    Associates a value with the provided key.

    Associates a value with the provided key.

    If the key is already present, it updates the value.
