Prototype

public static byte[] serialize(Serializable obj) 

Source Link

Document

Serializes an Object to a byte array for storage/serialization.

Usage

From source file:org.archive.state.ModuleTestBase.java

/**
 * Tests that the module can be serialized.  The value returned by 
 * {@link #makeModule} is serialized to a byte array, and then 
 * deserialized, and then serialized to a second byte array.  The results
 * are passed to {@link #verifySerialization}, which will simply compare
 * the two byte arrays for equality.  (That won't always work; see
 * that method for details)./* w ww . j  a v a2 s .c  o  m*/
 * 
 * <p>If nothing else, this test is useful for catching NotSerializable
 * exceptions for your module or classes it depends on.
 * 
 * @throws Exception   if the module cannot be serialized
 */
public void testSerializationIfAppropriate() throws Exception {
    Object first = makeModule();
    if (!(first instanceof Serializable)) {
        return;
    }
    byte[] firstBytes = SerializationUtils.serialize((Serializable) first);

    Object second = SerializationUtils.deserialize(firstBytes);
    byte[] secondBytes = SerializationUtils.serialize((Serializable) second);

    Object third = SerializationUtils.deserialize(secondBytes);
    byte[] thirdBytes = SerializationUtils.serialize((Serializable) third);

    // HashMap serialization reverses order of items in linked buckets 
    // each roundtrip -- so don't check one roundtrip, check two.
    //
    // NOTE This is JVM-dependent behaviour, and since <= 1.7.0_u51 this
    // ordering of serialisation cannot be relied upon. However, a TreeMap
    // can be used instead of a HashMap, and this appears to have
    // predictable serialisation behaviour.
    //
    // @see
    // http://stackoverflow.com/questions/22392258/serialization-round-trip-of-hash-map-does-not-preserve-order
    //
    // verifySerialization(first, firstBytes, second, secondBytes);
    verifySerialization(first, firstBytes, third, thirdBytes);
