Long2ObjectMap.Entry的用法

Long2ObjectMap.Entry<List<String>> data; 
 long longData = data.getLongKey();
 List<String> objectData = data.getValue();

得到entry:
 
Long2ObjectMap<List<String>> dataMap = new Long2ObjectOpenHashMap<>();
dataMap.put(...
 
Set<Long2ObjectMap.Entry<List<String>>> dataSet = dataMap.long2ObjectEntrySet();
 for(Long2ObjectMap.Entry<List<String>> data : dataSet) {...
