| Modifier and Type | Method and Description |
|---|---|
void |
cleanUpNullReferences()
Replying on the ConcurrentHashMap thread-safe iteration implementation the method will remove all entries holding
SoftReferences to gc-evicted objects.

|
java.util.Map<K,V> |
clearAll()
Clear the cache
|
boolean |
containsKey(java.lang.Object key)
Determines if the cache contains an entry for the specified key.
|
boolean |
containsValue(java.lang.Object value) |
java.util.Set<java.util.Map.Entry<K,V>> |
entrySet() |
V |
get(java.lang.Object key)
Gets a value from the cache
|
V |
getAndPut(K key,
MemoizeCache.ValueProvider<? super K,? extends V> valueProvider)
The implementation of `getAndPut` is not atomic
|
boolean |
isEmpty() |

keys()
Get all keys associated to cached values
|
java.util.Set<K> |
keySet() |
V |
put(K key,
V value)
Associates the specified value with the specified key in the cache.
|
void |
putAll(java.util.Map<? extends K,? extends V> m) |
V |
remove(java.lang.Object key)
Remove the cached value by the key
|
int |
size()
