| You can read a snapshot entry-by-entry for further processing or transformation into other formats. |
| |
| The following is an example of a snapshot reader that processes entries from a previously generated snapshot file. |
| |
| ``` pre |
| File mySnapshot = ... |
| SnapshotIterator<String, MyObject> iter = SnapshotReader.read(mySnapshot); |
| try { |
| while (iter.hasNext()) { |
| Entry<String, MyObject> entry = iter.next(); |
| |
| String key = entry.getKey(); |
| MyObject value = entry.getValue(); |
| |
| System.out.println(key + " = " + value); |
| } |
| } finally { |
| iter.close(); |
| } |
| ``` |
