A function template specialization might be ambiguous because template argument deduction might associate the specialization with more than one of the overloaded definitions .
在使用函数模板时,如果你定义了多个重载的特例化函数,可能导致模糊不清的调用,所以这时编译器会从中选择最特例的那个函数定义来调用。
When the compiler sees a call, it must know to expect a specialization for this version. Otherwise, the compiler is allowed to instantiate the function from the template definition.
当编译器看到一个函数调用时,它必须知道这个版本需要特化,否则,编译器将可能从模板定义实例化该函数。
Default arguments are not allowed on an explicit specialization of a function template.
不允许在函数模板的显式专用化上使用默认参数。
The full specialization is no longer a template. It's a concrete function.
函数模板全特化后不再是一个模板,它成为了一个函数的实现;
The full specialization is no longer a template. It's a concrete function.
