persistent data structure

基本解釋

Partially persistent data is a persistent data structure that allows updates to the latest version only.
部分持久數(shù)據(jù)是一種僅允許對(duì)最新版本更新的持久數(shù)據(jù)結(jié)構(gòu)。
Fully persistent data is a persistent data structure that both maintains and allows updates to all versions of its data.
完全持久數(shù)據(jù)是一種維護(hù)其數(shù)據(jù)的所有版本并允許對(duì)這些版本更新的持久數(shù)據(jù)結(jié)構(gòu)。
In short, the idea is to turn a persistent data structure into a transient before a series of modifications; the call transient achieves that.
簡(jiǎn)單來(lái)說(shuō)，這種思想就是在大量修改之前將一個(gè)持久數(shù)據(jù)結(jié)構(gòu)轉(zhuǎn)換為一個(gè)transient；調(diào)用transient即可完成這個(gè)功能。
