| 12 | <p>Here is the class diagram of a sample Java module 'GenListModule' in the
|
|---|
| 13 | preprocessing stage</p>

| 17 | <p>We use GenListModule which extends AbstractModule to control the whole
|
|---|
| 18 | program logic of this module. MapReader is used to parse the input xml
|
|---|
| 19 | file. It also implements the org.xml.sax.ContentHandler. Is used to
|
|---|
| 20 | handle different information in xml file, collect and write the information
|
|---|
| 21 | we need to class Content. ListWriter reads the information from class
|
|---|
| 22 | GenListModule and outputs those lists into the intermediate files. </p>
|
|---|
| 23 | <p>Here is the sequence diagram of the example. </p>

| 26 | </p>
|
|---|
| 27 | <p>GenListModule first creates MapReader and ListWriter. Then GenListModule
|
|---|
| 28 | calls MapReader to read and parse the input file. In order to process the
|
|---|
| 29 | large input file, we choose SAX Parser as the parser and each time we only
|
|---|
| 30 | process one file and keep the list of files we will process later in the
|
|---|
| 31 | waiting list of GenListModule. After the parse process is
|
|---|
| 32 | over, GenListModule gets the result content from MapReader. Then
|
|---|
| 33 | GenListModule processes the content and set the content to ListWriter. Then
|
|---|
| 34 | it calls ListWriter to output the information to intermediate file.</p>
