Returns a string representation of the object.

Usage

From source file:Main.java

/***
 * Serialize an object into xml string./*from w  w  w . j a v a2 s. co m*/
 * 
 * @param obj
 *            object to serialize
 * @return Xml string represents the object
 */

    final OutputStream bufferStream = new ByteArrayOutputStream();

    // Create XML encoder.
    final XMLEncoder xenc = new XMLEncoder(bufferStream);

    xenc.writeObject(obj);
    // Need to close the XMLEncoder to flush.
    xenc.close();

    final String serializedString = bufferStream.toString();

    // JavaDoc indicates that we will not need to close
    // a ByteArrayOutputStream. From JavaDoc:
    // Closing a ByteArrayOutputStream has no effect. The methods
    // in this class can be called after the stream has been closed
    // without generating an IOException.
    //
    // bufferStream.close();

    return serializedString;
