simple pointer meaning in English
单指针
Examples
- Objects differ exactly when the array indices representing them differ , i . e . , a simple pointer comparison is sufficient
元素对象不同也就是他们在数组中对应的序号不同，也就是仅仅比较元素对应的指针就足够了。 - Developers who have implemented sophisticated memory management schemes for non - garbage - collected languages may be surprised at how inexpensive allocation is - a simple pointer addition - in a copying collector
为非垃圾收集语言实现了复杂内存管理方案的开发人员可能会对复制收集器中廉价的内存分配感到吃惊就是指针加法这么简单。 - For example , members do not need to take a start index as a parameter because simple pointer arithmetic can be used to supply the pointer address as the pointer s base address added to the desired start index
例如，成员不需要将起始索引作为参数，因为可以使用简单的指针算法来提供指针地址，该指针地址作为添加到相应起始索引位置的指针基地址。 - This not only improves locality of reference of the user program and eliminates heap fragmentation , but also greatly reduces the cost of object allocation - object allocation becomes a simple pointer addition on the top - of - heap pointer
这不仅改进了用户程序的引用区域性并消除了堆碎片，而且极大地减少了对象分配的成本对象分配变成了在堆顶部的指针上增加指针。
