public static java.lang.Object	deserialize(java.io.InputStream inputStream) Deserialze an object from an InputStream param inputStream the serialized object input stream, must not be null return the deserialized object throws IOException, ClassNotFoundException if (inputStream == null) { throw new IllegalArgumentException("The inputStream argument cannot be null"); } ObjectInputStream inStream = null; try { // stream closed in the finally inStream = new ObjectInputStream(inputStream); return inStream.readObject(); } finally { try { if (inStream != null) { inStream.close(); } } catch (IOException ex) { // ignore } }
public static java.lang.Object	deserialize(byte[] objectBytes) Deserialize an object from a byte array param objectBytes the serialized object, can not be null return the deserialized object throws IOException, ClassNotFoundException if (objectBytes == null) { throw ValidationException.invalidNullMethodArguments(); } ByteArrayInputStream inStream = new ByteArrayInputStream(objectBytes); return deserialize(inStream);
public static void	serialize(java.io.Serializable obj, java.io.OutputStream outputStream) Serialize the object to an OutputStream param obj the object to serialize to bytes param outputStream the stream to write to, can not be null throws IOException if (outputStream == null) { throw ValidationException.invalidNullMethodArguments(); } ObjectOutputStream outStream = null; try { // stream closed in the finally outStream = new ObjectOutputStream(outputStream); outStream.writeObject(obj); } finally { try { if (outStream != null) { outStream.close(); } } catch (IOException ex) { // ignore; } }
public static byte[]	serialize(java.io.Serializable obj) Serialize the object to a byte array param obj the object to serialize to bytes return a byte[] of the obj throws IOException ByteArrayOutputStream outStream = new ByteArrayOutputStream(512); serialize(obj, outStream); return outStream.toByteArray();
