这几个接口都处在java.util.function包下，Consumer（消费型），Supplier（供给型）、Predicate（判断型）...
I need to call LLVMGetFunctionAddress like the C code above in Java, however it returns a pointer and I need to convert it to (int (*)(int, int)) function. More specifically, I guess the code would be like: long funAddr = LLVMGetFunctionAddress(engine, "sum") new Pointer { //so...
这是因为parameters是in的,dll中不会对这个参数做修改,而returnValue是out的,dll返回时候要把返回值写入这个 StringBuilder的缓冲区。 原本的想法是用C++写一个桥来调用dll,不过在.net 2.0 中,框架直接提供了 Marshal.GetDelegateForFunctionPointer 来转换一个函数指针为一个委托,这就方便多拉。请看下面代码,注意看 ...
<type_traits>的is_function_pointer <> 为什么type(object)返回<class 'type'>而不是<class 'object'>? type type- Flowtype可以自动注释变量的类型吗? type=1::importance():type=2可以工作,但不能随机森林 为什么std::set中有key_type和value_type ...
其实throw s4.get(),大伙们想想,s4.get其实就是一个NUllPointerException对象。那么我把这个对象throw出去,不就也是抛异常了吗 一个道理。 生产者的抽象逻辑就是:什么都不用入参,返给外界一个生产出来的对象,和消费者的逻辑是完全相反的。这就是生产者逻辑【当然,不用想的那么离谱,比如还要原料才能生产啥的,这...

Since this method takes only one Long parameter (4-bytes in size), why is the method removing 8 bytes from the stack? Because there's an extra parameter pushed onto stack before the call: the pointer to the object for which we're calling the procedure (aka the this pointer). To ...
