Example 1
@Test
public void testDouble() {
  double val = TEST_DOUBLE;
  String valString = Double.toString(val);
  HiveDynamoDBType ddType = HiveDynamoDBTypeFactory.getTypeObjectFromHiveType(DOUBLE_OBJECT_INSPECTOR);
  AttributeValue expectedAV = new AttributeValue().withN(valString);
  AttributeValue actualAV = ddType.getDynamoDBData(val, DOUBLE_OBJECT_INSPECTOR, false);
  assertEquals(expectedAV, actualAV);
  Object actualDouble = ddType.getHiveData(actualAV, DOUBLE_OBJECT_INSPECTOR);
  assertEquals(val, actualDouble);

  LazyDouble ld = new LazyDouble(LAZY_DOUBLE_OBJECT_INSPECTOR);
  initLazyObject(ld, valString.getBytes(), 0, valString.length());
  actualAV = ddType.getDynamoDBData(ld, LAZY_DOUBLE_OBJECT_INSPECTOR, false);
  actualDouble = ddType.getHiveData(actualAV, DOUBLE_OBJECT_INSPECTOR);
  assertEquals(val, actualDouble);
