  15.  * <p> An <code>InputObject</code> is the interface used by the

  16.  * presentation block to get programming language typed data from data

  17.  *  encoded in a message. </p>

  18.  *

  19.  * <p> The implementation of an <code>InputObject</code> contains the

  20.  * encoded data.  When the presentation block asks for data the

  21.  * implementation of <code>InputObject</code> is responsible for converting

  22.  * the encoded representation of the data to the types expected by the

  23.  * programming language.</p>

  24.  *

  25.  * <p>A particular <em>encoding</em> would subclass

  26.  * <code>InputObject</code>.  The subclass would provide methods to get

  27.  * the data types appropriate to the presentation block (e.g., simple

  28.  * types such as int or boolean, all the way to any type derived from

  29.  * <code>java.io.Serializable</code>.).</p>

  30.  *

  31.  * <p>Note: the protocol block may also use the <code>InputObject</code> to

  32.  * obtain header metadata.</p>
