类概要

类	说明
Arrs	Array tools
Collects	Collection utilities
CopyOnWriteHashMap<K,V>	An immutable map whose writes result in a new copy of the map to be created.
LinkedTreeMap<K,V>
MultiKeyMap<V>
NonAbsentHashMap<K,V>	Avoid the follower code: Map> map = new HashMap>(); List list = map.get(key); if(list==null){ list = new ArrayList(); map.put(key, list); } list.add(e); using this class, your code will be: Supplier> supplier = new Supplier>(){ public List get(K key){ return new ArrayList(); } }; Map> map = new NonAbsentHashMap>(); map.get(key).add(e);
Pipeline<E>
PrimitiveArrays	Primitive array wrapper
PropertiesAccessor
StringMap	A map with key, value are String.
StringMapAccessor	A accessor for a StringMap
Tuple
WheelQueue<E>
WrappedNonAbsentMap<K,V>	Avoid the follower code: Map> map = new HashMap>(); List list = map.get(key); if(list==null){ list = new ArrayList(); map.put(key, list); } list.add(e); using this class, your code will be: Supplier> supplier = new Supplier>(){ public List get(K key){ return new ArrayList(); } }; Map> map0 = new HashMap>(); Map> map = WrapedNonAbsentMap.wrap(map0, supplier); map.get(key).add(e);
