[jira] [Updated] (FLINK-3782) ByteArrayOutputStream and
ObjectOutputStream should close
[ https://issues.apache.org/jira/browse/FLINK-3782?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chenguang He updated FLINK-3782:
--------------------------------
Description:
@Test
public void testSerializability() {
try {
Collection<ElementType> inputCollection = new ArrayList<ElementType>();
ElementType element1 = new ElementType(1);
ElementType element2 = new ElementType(2);
ElementType element3 = new ElementType(3);
inputCollection.add(element1);
inputCollection.add(element2);
inputCollection.add(element3);
@SuppressWarnings("unchecked")
TypeInformation<ElementType> info = (TypeInformation<ElementType>) TypeExtractor.createTypeInfo(ElementType.class);
CollectionInputFormat<ElementType> inputFormat = new CollectionInputFormat<ElementType>(inputCollection,
info.createSerializer(new ExecutionConfig()));
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(buffer);
out.writeObject(inputFormat);
ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(buffer.toByteArray()));
Object serializationResult = in.readObject();
assertNotNull(serializationResult);
assertTrue(serializationResult instanceof CollectionInputFormat<?>);
@SuppressWarnings("unchecked")
CollectionInputFormat<ElementType> result = (CollectionInputFormat<ElementType>) serializationResult;
GenericInputSplit inputSplit = new GenericInputSplit(0, 1);
inputFormat.open(inputSplit);
result.open(inputSplit);
while(!inputFormat.reachedEnd() && !result.reachedEnd()){
ElementType expectedElement = inputFormat.nextRecord(null);
ElementType actualElement = result.nextRecord(null);
assertEquals(expectedElement, actualElement);
}
}
catch(Exception e) {
e.printStackTrace();
fail(e.toString());
}
}
was:
