## [Java] Class ConcurrentSoftCache<K, V>

- org.codehaus.groovy.runtime.memoize.ConcurrentSoftCache

-     public class ConcurrentSoftCache<K, V>
      extends ConcurrentCommonCache

  Represents concurrent cache holding SoftReference instance as value

  Type Parameters:
    `K` - key type
    `V` - real value type

- - ### Constructor Detail

    - #### public ConcurrentSoftCache()

      Constructs a cache with unlimited size

    - #### public ConcurrentSoftCache(int initialCapacity, int maxSize, EvictionStrategy evictionStrategy)

      Constructs a cache with limited size

      Parameters:
        `initialCapacity` - initial capacity of the cache
        `maxSize` - max size of the cache
        `evictionStrategy` - LRU or FIFO, see org.codehaus.groovy.runtime.memoize.EvictableCache.EvictionStrategy

    - #### public ConcurrentSoftCache(int initialCapacity, int maxSize)

      Constructs a LRU cache with the specified initial capacity and max size. The LRU cache is slower than LRUCache

      Parameters:
        `initialCapacity` - initial capacity of the LRU cache
        `maxSize` - max size of the LRU cache

    - #### public ConcurrentSoftCache(int maxSize)

      Constructs a LRU cache with the default initial capacity(16)

      Parameters:
        `maxSize` - max size of the LRU cache
      See Also:
        ConcurrentSoftCache(int, int)

    - #### public ConcurrentSoftCache(Map<K, SoftReference<V>> map)

      Constructs a cache backed by the specified Map instance

      Parameters:
        `map` - the Map instance

  - ### Method Detail

    - #### @Override
      public Object convertValue(SoftReference<V> value)

      {@inheritDoc}
