A <CODE>Service</CODE> is categorized by the type of processing it performs:<ul> <li><em>A pre-processing service pre-processes input data for the command being processed. It is associated with the <CODE>PROCESS_INPUT_DATA</CODE> phase.</em></li> <li><em>A command processing service processes the input data and generates output data. It is associated with the <CODE>PROCESS_COMMAND</CODE> phase.</em></li> <li><em>A post-processing service post-processes the generated output data. It is associated with the <CODE>PROCESS_OUTPUT_DATA</CODE> phase.</em></li> </ul> The dispatcher simply dispatches incoming <code>APDU</code> object containing the command being processed to the registered services.<P><P><DL><DT><B>Version:</B></DT> <DD>1.0</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%"
