Java Iterator等效于C？ (带代码)

大家好.一位朋友为我编写了一些Java代码,我很容易将其转换为C,但我对C中的Java迭代器的等价物非常好奇.这是代码,我很可能希望将数据返回到向量中.任何帮助表示赞赏

public class RLEIterator
extends RegionIterator
{
    public int reg = 0;
    public int mode = 0;
    public int skip = 0;
        // mode is the number of IDs that are valid still (count down)
        // skip is used after we run out of mode IDs,and move forward
        //   The goal is,to always have a valid 'hasNext' state,after
        // an ID is read via 'next'. Thus,the initial search,and then
        // the reading forward if mode == 0,after the ID is found.
    public int i;

    public RLEIterator()
    {
        // Need to set up the skip of an initial part,so we can
        // correctly handle there not being anything,despite there
        // being data encoded.

        int comp;
        i = 0;

        while ((mode == 0) && (i

++it

*it

--it
