Rise time shows how quickly the filter catches up with sudden changes in input, while overshoot, ringing, and settling time are indications of how well a filter can settle down after it has responded to a sudden change in input. A filter’s response to a step function does not reveal all...
Not only that, but when a function returns only one object, this function can be nested with other function calls, while returning data with in/out parameters disallows this nesting. When objects are returned with this "better" method, usually the developer once again has only two choices: ...
If there is some activity that must be performed before you no longer need an object, you must perform that activity yourself. Java has no destructor or similar concept, so you must create an ordinary method to perform this cleanup.
deleteobjPtr; or delete[] objPtr; where objPtr is declared to be a pointer to the base class but actually contains a pointer to an object of a derived class. 2.3.7. Java destructor and garbage collection Java has no destructor. Instead, the garbage collector examines the active references to...

如果hasDisplayGeometryChanged()返回true,或者使用ARSession.setDisplayGeometry()设置了新的显示大小就需要更新纹理坐标,需要调用该方法更新纹理映射坐标;否则不需要更新。 Public Methods acquireCameraImage Method public Image acquireCameraImage() 在camera状态为tracking状态下,获取当前帧对应的图像,返回图像格式为YUV...
stk represents the effect on the depth of the expression stack. For example, the _nop instruction does not perform any operation, so it has no effect on the depth of the expression stack. The value of stk is 0; when _iconst_0 is used to push 0 into the stack, the depth of the st...
