  33  * <p> An <code>InputObject</code> is the interface used by the
  34  * presentation block to get programming language typed data from data
  35  *  encoded in a message. </p>
  36  *
  37  * <p> The implementation of an <code>InputObject</code> contains the
  38  * encoded data.  When the presentation block asks for data the
  39  * implementation of <code>InputObject</code> is responsible for converting
  40  * the encoded representation of the data to the types expected by the
  41  * programming language.</p>
  42  *
  43  * <p>A particular <em>encoding</em> would subclass
  44  * <code>InputObject</code>.  The subclass would provide methods to get
  45  * the data types appropriate to the presentation block (e.g., simple
  46  * types such as int or boolean, all the way to any type derived from
  47  * <code>java.io.Serializable</code>.).</p>
  48  *
  49  * <p>Note: the protocol block may also use the <code>InputObject</code> to
  50  * obtain header metadata.</p>
