这可能比使用std::back_inserter更有效的原因是,insert()将预先知道结果大小,因此最多只需要完成一次分配,然后不需要执行任何实际插入的大小检查。 这太难于编写了,所以我建议对这个命名为extend()的代码进行基于范围的重载 代码语言:javascript 运行 AI代码解释 template <class T, class Range> void extend(std::...

}// Method 2: Same as 1 but pre-extend the vector by the size of the array using reserve{ dataVec.reserve(dataVec.size() + dataArraySize);copy(&dataArray[0], &dataArray[dataArraySize],back_inserter(dataVec)); }// Method 3: Memcpy{ dataVec.resize(dataVec.size() + dataArraySize);m...

Middleware allows you to easily extend tilesplash to add additional functionality. Middleware is defined like this: varuserMiddleware=function(req,res,tile,next){tile.logged_in=true;tile.user_id=req.query.user_id;next();}; You can layer include this in your layers ...
