你能做一个C ++通用函数吗? [英] Can you make a C++ generic function?
问题描述
是否可以创建一个通用的C ++函数 foo
?
Is it possible to create a generic C++ function foo
?
foo(Object bar, Object fred)
{
//code
}
其中如果两个对象被识别,则比较它们并返回一个比较值,否则返回一些其他值以指示不可能进行比较。
in which that if the two objects are recognized, they are compared and a comparison value is returned otherwise some other value is returned to indicate a comparison was not possible?
我要求在泛化排序类的情况下,在这种情况下,您可以使用此方法,并且当您导出要对其排序的新对象时,您添加到此foo函数,一个方法来对新类型of Object。
I ask in the case of genericizing a sorting class, in which case you can use this method, and when you derive new objects you want to sort, you add to this foo function, a method on which to sort the new type of Object.
推荐答案
我认为你急需 模板 !
您可以编写一个模板函数,然后为所述类型写一个特殊化来做特定的事情需要。
I think you are in dire need of Templates!
You can write a template function and then write a specialization for the said types to do something specific if the need be.
