仔细看一下联机帮助:The reserved word inherited plays a special role in implementing polymorphic behavior. It can occur in method definitions, with or without an identifier after it.
If inherited is followed by the name of a member, it represents a normal method call or reference to a property or field梕xcept that the search for the referenced member begins with the immediate ancestor of the enclosing method抯 class. For example, when
inherited Create(...);
occurs in the definition of a method, it calls the inherited Create.
When inherited has no identifier after it, it refers to the inherited method with the same name as the enclosing method. In this case, inherited takes no explicit parameters, but passes to the inherited method the same parameters with which the enclosing method was called. For example,
inherited;
occurs frequently in the implementation of constructors. It calls the inherited constructor with the same parameters that were passed to the descendant.
inherited的作用是调用父类的成员函数,不加函数名是调用父类中同名的方法。
