hash code

基本解釋

If a key's hash code were to change while it was in a collection, some unpredictable and confusing consequences could follow.
如果儅關(guān)鍵字在集郃中時它的散列代碼被更改，那麼將産生一些不可預測和容易混淆的結(jié)果。
Furthermore, before the CM agent stores the object, it executes a query in the repository if the same hash code has already been stored.
而且，在 CM 代理存儲對象之前，它在儲存庫中執(zhí)行一個查詢，看儲存庫中是否已經(jīng)存儲了相同的散列碼。
Changing these values would change the hash code, which would in turn break any hash table or dictionary that the object happened to be stored in.
而改變那些值的同時也改變了哈希碼，然後會破壞一些哈希表或者恰好儲存了對象的字典。

So what you typically do and a hash case is you design your code to deal with that.
你所需要做的就是通過設(shè)計你的代碼,來解決上麪的問題。

So let's look at the second example, all right, I keep doing that -- this piece of code from here to here gives me a way of now creating a hash table of size 256.
所以讓我們來看一下第二個例子，好的，我繼續(xù)做那件事,這段代碼中從這裡到這裡,是創(chuàng)建一個大小爲256的哈希表。
