I have this code:

我有这个代码：

Element excludeFilterElementMerged = excludeFilter.elements.get(0);
for (model.rest.filter.Segment.Element elementExcl : excludeFilter.elements) {
    filterPosition++;
    excludeFilterElementMerged.isIncluded = "false";

    if (filterPosition % 10 == 0 || filterPosition == excludeFilter.elements.size()){
        elements.add(excludeFilterElementMerged);
        excludeFilterElementMerged = elementExcl;
    }

    excludeFilterElementMerged.filter.criteria.addAll(elementExcl.filter.criteria);
    excludeFilterElementMerged.filter.statement += " OR "+elementExcl.filter.statement;

}
