它创建了一个对象的副本,因此当评估lambda时,它的this指针引用副本,而不是原始对象. 可以用C++ 14实现[tmp = *this]吗?它可以,但[*this]更方便,因为代码可以在没有前缀成员访问权限的情况下移动tmp..否则,特别是[=, tmp = *this]当你想要引用副本时,可能会意外地引用原始对象的成员(特别是如果你习惯于剪切...
在C++中,lambda表达式是一种可以捕获其所在作用域内变量的匿名函数对象。Lambda表达式的捕获列表(capture list)用于指定哪些外部变量将被捕获到lambda表达式的内部作用域中,以及是以什么方式(值捕获或引用捕获)进行捕获。捕获列表可以是空的,也可以包含一个或多个变量名,前面可以带有&(引用捕获)或=(值捕获)符号,...

Add an error node child and force its parent to be this node. addErrorNode(Token) Add a child to this node based upon badToken. It creates a ErrorNode rather than using [Token)](xref:Parser%23createErrorNode(ParserRuleContext%2C). I'm leaving this in for compatibility but the parser ...

2c). One reason for this phenomenon could be that phosphate has a high buffering capacity which, at higher concentrations, suppresses the acidic environment needed for in-situ CO2 generation and simultaneously acts as a proton donor for HER43,44. We probed the electrolyzer using electrochemical ...
