是否有推动作用的Java某处等效:: multi_index？ [英] Is there an equivalent of boost::multi_index for Java someplace?

问题描述

我在multi_index在云雀昨晚跌跌撞撞，而我冲击了反对的集合，我需要通过3个不同的键值来访问，也有平衡的数组语义。嗯，我得到了在升压:: multi_index我的两个愿望（3个不同的键值）之一。

I stumbled upon multi_index on a lark last night while pounding my had against a collection that I need to access by 3 different key values, and also to have rebalancing array semantics. Well I got one of my two wishes (3 different key values) in boost::multi_index.

我很好奇，如果在Java世界中存在类似的话。

I'm curious if anything similar exists in the Java world.
