How to use

getRange

method

in

org.apache.bookkeeper.mledger.util.RangeCache

Collection<EntryImpl> cachedEntries = entries.getRange(firstPosition, lastPosition);

@Test
void getRange() {
  RangeCache<Integer, RefString> cache = new RangeCache<>();
  cache.put(0, new RefString("0"));
  cache.put(1, new RefString("1"));
  cache.put(3, new RefString("3"));
  cache.put(5, new RefString("5"));
  assertEquals(cache.getRange(1, 8),
      Lists.newArrayList(new RefString("1"), new RefString("3"), new RefString("5")));
  cache.put(8, new RefString("8"));
  assertEquals(cache.getRange(1, 8),
      Lists.newArrayList(new RefString("1"), new RefString("3"), new RefString("5"), new RefString("8")));
  cache.clear();
  assertEquals(cache.getSize(), 0);
  assertEquals(cache.getNumberOfEntries(), 0);
}

Collection<EntryImpl> cachedEntries = entries.getRange(firstPosition, lastPosition);

Collection<EntryImpl> cachedEntries = entries.getRange(firstPosition, lastPosition);
