Constructor Detail- 
ConcurrentSoftCachepublic ConcurrentSoftCache() Constructs a cache with unlimited size
 - 
ConcurrentSoftCachepublic ConcurrentSoftCache(int initialCapacity, int maxSize, EvictableCache.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- EvictableCache.EvictionStrategy
 
 - 
ConcurrentSoftCachepublic ConcurrentSoftCache(int initialCapacity, int maxSize)Constructs a LRU cache with the specified initial capacity and max size. The LRU cache is slower thanLRUCache- Parameters:
- initialCapacity- initial capacity of the LRU cache
- maxSize- max size of the LRU cache
 
 - 
ConcurrentSoftCachepublic ConcurrentSoftCache(int maxSize) Constructs a LRU cache with the default initial capacity(16)- Parameters:
- maxSize- max size of the LRU cache
