In my processing program, I added an object into a global ArrayList called items in my draw function. Here is the class. Here is my draw function. I tried printing the size of items in my mouseClicked... How to return an object that was deleted?
This construct suspends execution of the current function. The address of the function is placed into a list of waiting functions. Waiting functions are "unfrozen" after therunWaitscall, which can be performed only in the C++ part of the application. Unigine runs functions from the waiting list...
Predicate必须满足函数对象(FunctionObject)。 - pred()必须为合法的表达式,且其类型与值类别必须符合可布尔测试(BooleanTestable)要求。 返回值 1-2)(无) 3)在返回调用方前pred()的最新结果。 异常 1)不抛出 2,3)pred抛出的任何异常。 注解 重载(3)的返回值指示pred是否求值为true,与是否有请求过停止无关。

The Microsoft-specific function name cwait is a deprecated alias for the _cwait function. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported...

Predicate必须满足函数对象(FunctionObject)。 - pred()必须为合法的表达式,且其类型与值类别必须满足可布尔测试(BooleanTestable)。 异常 1)不抛出。 2)pred抛出的任何异常。 注解 notify_one()/notify_all()的效果,与wait()/wait_for()/wait_until()的三个原子部分(解锁+等待,唤醒,以及锁定)的每一者,以一...
Using thewaitKey()Function in OpenCV ThewaitKey()function in OpenCV is used to wait for a specific time interval and then close the active image window. We can pass the delay in milliseconds inside thewaitKey()function, and the function will wait for that specific time, and then it will...
If we only have thisMain_Func(), the whole program will be asynchronous, but we will add other functions in the next example. Inside this function, we will use twoprint()functions. And, in between, we are going to sleep, but we are not going to sleep withtime.sleep(); we are goin...
cppreference上面是这么说的: The execution of the current thread (which shall have lockedlck'smutex) is blocked untilnotified. At the moment of blocking the thread, the function automatically callslck.unlock(), allowing other locked threads to continue. ...
