For example , a constraint may disallow multiple inheritance , or it may require that a class must have a particular type of attribute 例如,一個限制可能不允許多重繼承,或者是它可能需要一個類必須具備一個特殊的屬性類型。
Although multiple inheritance is not allowed in classes , classes can implement multiple interfaces , which can effectively accomplish the same ends 雖然類中不允許有多重繼承,但類可以實現(xiàn)多個接口,這樣可以有效地實現(xiàn)同樣的目的。
Some of those features directly conflict with each other , like java s single inheritance model and c s multiple inheritance model , for example 這幾種語言中甚至有許多特性是互相矛盾的。例如java只支持單一繼承,而c + +則可以有多個父類。
Perl supports single or multiple inheritance hierarchies , encapsulation , and polymorphism , but only through external modules or programmer agreement Perl支持單一繼承或多繼承、封裝以及多態(tài),但這僅僅是通過外部模塊或程序員的協(xié)同來實現(xiàn)的。
Unlike languages that permit multiple inheritance , visual basic permits only single inheritance in classes ; that is , derived classes can have only one base class 與允許多重繼承的語言不同, visual basic只允許類中有單一繼承,即派生類只能有一個基類。
Tujia inheritance experienced a course from multiple inheritance , to the unitary paternal inheritance , to the coexistence of paternal and maternal inheritance 摘要土家族的承嗣經(jīng)歷了由“多元承嗣單一的父系血緣承嗣父系與父母雙向承嗣并存”的過程。
With multiple inheritance comes the question of method resolution order : the order in which a class and its bases are searched looking for a method of a given name 在多重繼承的情況下才會出現(xiàn):對于一個給定名字的方法,以何種順序在類和它的基類中進(jìn)行查找。
Multiple inheritance is not possible in c # using classes ; however , you can implement multiple interfaces . this is a simple example of inheriting characteristics of multiple interfaces 在c #類中使用多重繼承是不可能的,但是你可以實現(xiàn)多個接口。這是一個簡單的用多接口來模仿多重繼承的例子。
Using multiple interfaces - multiple inheritance is not possible in c # using classes ; however , you can implement multiple interfaces . this is a simple example of inheriting characteristics of multiple interfaces 在c #類中使用多重繼承是不可能的,但是你可以實現(xiàn)多個接口。這是一個簡單的用多接口來模仿多重繼承的例子。
Multiple inheritance is a feature of some object-oriented computer programming languages in which a class can inherit characteristics and features from more than one superclass. It is distinct to single inheritance, where a class may only inherit from one particular superclass.
