邏輯值

multiple-valued logic and continuous logic 多值邏輯與連續邏輯 orAllKeys: this reverses the default behaviors that involve a logical AND of all keys. orallkeys:這個修飾詞使得默認的對所有鍵值的邏輯與操作的行為變成邏輯或操作的行為。 You can’t use a non-boolean as if it were a boolean in a logical expression as you can in C and C++. 與在c及c++中不同，不可將一個非布爾值當作布爾值在邏輯表達式中使用。 The returned businessList contains businessInfo structures matching any of the URL's passed (logical OR). 返回的businesslist包含了能夠匹配傳入的url值之一(邏輯或)的businessinfo結構。 As a result, all the parts of a logical expression might not be evaluated. 因此，一個邏輯表達式的所有部分都有可能不進行求值。
