Constructor Summary

Constructors
Constructor and description
`UnlimitedConcurrentCache ()` Constructs a cache with unlimited size
`UnlimitedConcurrentCache (int initialCapacity)` Constructs a cache with unlimited size and set its initial capacity
`UnlimitedConcurrentCache (Map<? extends K, ? extends V> m)` Constructs a cache and initialize the cache with the specified map

Methods Summary

Methods
Type Params	Return Type	Name and description
	`public void`	`cleanUpNullReferences()` Replying on the ConcurrentHashMap thread-safe iteration implementation the method will remove all entries holding SoftReferences to gc-evicted objects.
	`public Map<K, V>`	`clearAll()` Clear the cache
	`public boolean`	`containsKey(Object key)` Determines if the cache contains an entry for the specified key.
	`public boolean`	`containsValue(Object value)`
	`public Set<Entry<K, V>>`	`entrySet()`
	`public V`	`get(Object key)` Gets a value from the cache
	`public V`	`getAndPut(K key, ValueProvider<? super K, ? extends V> valueProvider)` Try to get the value from cache.
	`public boolean`	`isEmpty()`
	`public Set<K>`	`keySet()`
	`public Set<K>`	`keys()` Get all keys associated to cached values
	`public V`	`put(K key, V value)` Associates the specified value with the specified key in the cache.
	`public void`	`putAll(Map<? extends K, ? extends V> m)`
	`public V`	`remove(Object key)` Remove the cached value by the key
	`public int`	`size()` Get the size of the cache
	`public Collection<V>`	`values()` Get all cached values

- Constructor Detail
  - public UnlimitedConcurrentCache()
    
    Constructs a cache with unlimited size
  - public UnlimitedConcurrentCache(int initialCapacity)
    
    Constructs a cache with unlimited size and set its initial capacity
    Parameters:
    initialCapacity - the initial capacity
  - public UnlimitedConcurrentCache(Map<? extends K, ? extends V> m)
    
    Constructs a cache and initialize the cache with the specified map
    Parameters:
    m - the map to initialize the cache
- Method Detail
  - @Override public void cleanUpNullReferences()
    
    Replying on the ConcurrentHashMap thread-safe iteration implementation the method will remove all entries holding SoftReferences to gc-evicted objects.
  - @Override public Map<K, V> clearAll()
    
    Clear the cache
    Returns:
    returns the content of the cleared map
  - @Override public boolean containsKey(Object key)
    
    Determines if the cache contains an entry for the specified key.
    Parameters:
    key - key whose presence in this cache is to be tested.
    Returns:
    true if the cache contains a mapping for the specified key
  - @Override public boolean containsValue(Object value)
  - @Override public Set<Entry<K, V>> entrySet()
  - @Override public V get(Object key)
    
    Gets a value from the cache
    Parameters:
    key - the key whose associated value is to be returned
    Returns:
    the value, or null, if it does not exist.
  - @Override public V getAndPut(K key, ValueProvider<? super K, ? extends V> valueProvider)
    
    Try to get the value from cache. If not found, create the value by MemoizeCache.ValueProvider and put it into the cache, at last return the value.
    Parameters:
    key
    valueProvider - provide the value if the associated value not found
    Returns:
    the cached value
  - @Override public boolean isEmpty()
  - @Override public Set<K> keySet()
  - @Override public Set<K> keys()
    
    Get all keys associated to cached values
    Returns:
    all keys
  - @Override public V put(K key, V value)
    
    Associates the specified value with the specified key in the cache.
    Parameters:
    key - key with which the specified value is to be associated
    value - value to be associated with the specified key
    Returns:
    null, or the old value if the key associated with the specified key.
  - @Override public void putAll(Map<? extends K, ? extends V> m)
  - @Override public V remove(Object key)
    
    Remove the cached value by the key
    Parameters:
    key
    Returns:
    returns the removed value
  - @Override public int size()
    
    Get the size of the cache
