mapping function

基本解釋

You must retrieve the current identity and then use a mapping function to come up with a new identity.
您必須檢索儅前標識，然後使用映射函數生成一個新的標識。
The login module must retrieve the current identity and then use a mapping function to come up with a new identity.
登錄模塊必須檢索儅前標識，然後使用映射函數生成一個新的標識。
In this way, mapping of placement groups (and replicas) to storage devices does not rely on any metadata but instead on a pseudo-random mapping function.
這樣一來，放置組（以及副本）到存儲設備的映射就不用依賴任何元數據，而是依賴一個偽隨機的映射函數。

Well the idea of a hash, in fact, what's called a hash function is to have some way of mapping any kind of data into integers.
我要怎麼做？實際上想法還是哈希,通過一個哈希函數,把任何種類的數據都映射成整數。
