GS Collections是一个Java集合框架。它拥有兼容JDK的List,Set和Map实现。提供了丰富的API和一组工具类用于操作任何JDK兼容的Collections, Arrays, Maps 或 Strings。以下是一个示例代码:
MutableList<Person> people = FastList.newListWith(person1, person2, person3); MutableList<String> sortedLastNames = people.collect(Person.TO_LAST_NAME).sortThis(); System.out.println("Comma separated, sorted last names: " + sortedLastNames.makeString());
为什么要使用GS Collections?
- 提高可读性和减少重复迭代代码
- 实现了几个,高层次的迭代模式 (select, reject, collect, inject into, etc.)扩展自JDK接口的 “人性化”容器接口。
- 为 Collections, Arrays, Maps, 和 Strings提供了一个一致的迭代机制。
- 提供替代优化性能和内存使用的ArrayList,HashSet,HashMap。
- Performs more "behind-the-scene" optimizations in utility classes
- Encapsulates a lot of the structural complexity of parallel iteration and lazy evaluation
- Adds new containers including Bag, Interval, Multimap, and immutable versions of all types
- Has been under active development since 2005 and is a mature library
