null objects造句
例句與造句
- null object reference nothing in visual basic
空對象引用（在visualbasic中為 - a null object reference is pushed onto the stack
將空對象引用推送到堆棧上。 - thrown by the runtime only when a null object is referenced
僅當引用空對象時，才由運行庫引發(fā)。 - null object reference nothing
空對象引用（在visualbasic中為 - is thrown when an attempt is made to invoke a non-static method on a null object
當嘗試對空對象調用非靜態(tài)方法時，將引發(fā) - It's difficult to find null objects in a sentence. 用null objects造句挺難的
- the exception that is thrown when there is an attempt to dereference a null object reference
嘗試取消引用空對象引用時引發(fā)的異常。 - this provides the flexibility in type system design to map null objects to their corresponding xml types
這就為類型系統(tǒng)設計提供了將空（null）對象映射為其對應的xml類型的靈活性。 - transfers control if it represents an instance of an object for example, if it is not the null object reference; see
的別名）將在它表示對象實例時轉移控制（例如，在它不是空對象引用時；請參見 - however, this case-where a class manages its own memory-is one of the very few situations where explicitly nulling objects that are no longer needed is a good idea
但是這種情況由類管理其自己的內存是一種非常少見的情況，即顯式地消除不再需要的對象是一個好主意。 - the conventional way to have a reference refer to no-object is to provide an explicit singleton representing by convention a null object which often serves as a default argument to a function parameter
（讓引用引用空對象的常規(guī)方式是提供顯式的單一實例，按約定，該實例表示一個經常充當函數(shù)參數(shù)的默認變量的空對象）。 - because script code is late-bound, which means that calls against the object are not resolved until run-time, errors can include everything from referencing a null object to calling an undefined property or method
。因為腳本代碼是后期綁定的（這意味著直到運行時才會解析對象調用），所以可能包括一切錯誤，從引用空對象到調用未定義的屬性或方法。
