need-cast

基本解釋

In practice, arguments should not need casts when calling over-loaded functions: The need for a cast means that the parameter sets are designed poorly.
在實(shí)際應(yīng)用中，調(diào)用重載函數(shù)時(shí)應(yīng)盡量避免對(duì)實(shí)參做強(qiáng)制類(lèi)型轉(zhuǎn)換：需要使用強(qiáng)制類(lèi)型轉(zhuǎn)換意味著所設(shè)計(jì)的形參集合不合理。
In the event that such expressions are frequently created, this switch can be set to True, to automatically perform the needed cast.
如果需要頻繁創(chuàng)建這類(lèi)表達(dá)式,則可以將此切換設(shè)置為T(mén)rue以自動(dòng)執(zhí)行所需轉(zhuǎn)換。
I need a piece of string to tie this parcel up.
我需要一根細(xì)繩把這包裹扎起來(lái)。
I need some time to orient my thinking.
我需要一些時(shí)間來(lái)使我的思想適應(yīng)。
You need to filter the drinking water.
你需要把飲用水過(guò)濾。
