abstract function class
常见例句
- Classes derived from the abstract class must implement the pure virtual member function or they, too, are abstract classes.
由抽象類別衍生出來的類別必須實作純虛擬成員函式,否則它們也是抽象類別。 - You open the file by calling the in function of the DL_Dxf object and passing a pointer to a class that inherits from the DL_CreationAdapter abstract class.
通過調用 DL_Dxf 對象的 in 函數竝將指針傳遞給一個繼承 DL_CreationAdapter 抽象類來打開此文件。 - In a base class, abstract class is defined by declaring pure virtual function, a derived class must define all inherited pure virtual functions of its base classes to be concrete.
在基類中可以通過將虛函數聲明爲純虛函數的手段來定義抽象類,強制派生類在自己的類定義中實現虛函數的具躰功能。 返回 abstract function class
