From source file:com.ning.metrics.serialization.event.SmileEnvelopeEvent.java

/**

 * and with the same types as were written by writeExternal.
 *
 * @param in the stream to read data from in order to restore the object
 * @throws java.io.IOException if I/O errors occur
 *//*from  w w  w .j  a  v  a2  s. c o  m*/
