Example 7 with ObjectOutput

use of java.io.ObjectOutput in project hibernate-orm by hibernate.

the class DeleteOrphanTest method serialize.

private byte[] serialize(Object object) throws IOException {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    ObjectOutput out = new ObjectOutputStream(stream);

}

Example 8 with ObjectOutput

use of java.io.ObjectOutput in project Serial by twitter.

the class LegacySerial method toByteArray.

/**
 * Serialize the given value and compress the result bytes. This method should be used only for values
 * that may occupy large amount of memories. Do not use this method for small objects because the
 * compression incurs performance overheads and the compressed data cannot be inspected using
 * SerializationUtils.dumpSerializedData
 *
 * @param value the value to be serialized.
 * @param serializer the serializer used to serialize value.
 * @return compressed bytes of the serialized value.
 */
@Override
@NotNull
public <T> byte[] toByteArray(@Nullable T value, @NotNull Serializer<T> serializer) throws IOException {
    if (value == null) {
        return InternalSerialUtils.EMPTY_BYTE_ARRAY;
    }
    final ByteArrayOutputStream byteOutputStream = new ByteArrayOutputStream();
    ObjectOutput objectOutput = null;
    try {
        objectOutput = new ObjectOutputStream(byteOutputStream);
        serializer.serialize(mContext, new LegacySerializerOutput(objectOutput), value);
    } catch (IOException e) {
        throw e;
    } finally {

    }
    return byteOutputStream.toByteArray();
}

Example 9 with ObjectOutput

public void testSerialization() throws Exception {
    Map<String, IgfsMode> pathModes = new HashMap<>();
    pathModes.put("path1", PRIMARY);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ObjectOutput os = new ObjectOutputStream(bos);
    os.writeObject(attrs);
    os.close();
    IgfsAttributes deserializedAttrs = (IgfsAttributes) new ObjectInputStream(new ByteArrayInputStream(bos.toByteArray())).readObject();
    assertTrue(eq(attrs, deserializedAttrs));
}
