Detailed Description

template<typename ArgType, typename... Args>
class LibXR::CallbackBlock< ArgType, Args >

回调函数封装块，提供参数绑定与擦除调用入口 / Callback block with bound argument and erased invoke entry

Template Parameters

ArgType	绑定的第一个参数类型 / Type of the first bound argument
Args	额外的参数类型列表 / Additional argument types

Constructor & Destructor Documentation

CallbackBlock()

template<typename ArgType , typename... Args>

LibXR::CallbackBlock< ArgType, Args >::CallbackBlock ( FunctionType fun, ArgType && arg )

inline

构造回调块，绑定回调函数与参数 / Construct a callback block with bound function and argument

工厂层已经把 fun 收窄到了当前块真实需要的函数指针类型，因此这里不再保留 额外的模板参数做二次推导。 The factory has already narrowed fun to the exact function-pointer type required by this block, so there is no need to keep another template parameter here.

Parameters

fun	需要调用的回调函数 / Callback function to be invoked
arg	绑定的参数值 / Bound argument value
