Key: CASSANDRA-1775
URL: https://issues.apache.org/jira/browse/CASSANDRA-1775
Project: Cassandra
Issue Type: Bug
Components: API
Affects Versions: 0.6.6
Environment: apcahe cassandra 0.6.6
lib thrift r917130
Reporter: Igor Demydenko
Priority: Minor
SlicePredicate doesn't support the java.lang.Object.equals() method contract.
Execute following test:
public class SlicePredicateTest {
private static final String ENCODING = "UTF-8";
private static final String COLUMN_NAME = "ColumnName";
@Test
public void testEquals() throws Exception {
SlicePredicate predicate = new SlicePredicate();
predicate.setColumn_names(Arrays.asList(COLUMN_NAME.getBytes(ENCODING)));
SlicePredicate predicate2 = new SlicePredicate();
predicate2.setColumn_names(Arrays.asList(COLUMN_NAME.getBytes(ENCODING)));
SlicePredicate predicate3 = new SlicePredicate();
predicate3.setColumn_names(Arrays.asList(COLUMN_NAME.getBytes(ENCODING)));
assertFalse(predicate.equals(null)); // not null
assertTrue(predicate.equals(predicate)); // reflexivity
assertTrue(predicate.equals(predicate2) &&
predicate2.equals(predicate)); // symmetry
assertTrue(predicate.equals(predicate2) &&
predicate2.equals(predicate3)
&& predicate.equals(predicate3)); // transitivity
}
}
