FileListRenderer

java.lang.Object
- com.ibm.as400.util.html.FileListRenderer

All Implemented Interfaces:

java.io.Serializable
```
public class FileListRenderer
extends java.lang.Object
implements java.io.Serializable
```
The FileListRenderer class renders the name field for directories and files in a FileListElement.
If the behavior of the default FileListRenderer is not desired, subclass FileListRenderer and override the appropriate methods until the FileListElement achieves the desired behavior.
Subclassing FileListRenderer will allow your servlet to include/exclude or change the action of any directory or file in the FileListElement. For example, if a servlet did not want users to see any *.exe files, A subclass of FileListRenderer would be created and the new class would override the getFileName() method to figure out if the File object passed to it was a *.exe file, if it is, null could be returned, which would indicate that the file should not be displayed.
Overriding the getRowData method will allow the addition of columns in the row data and also enable the reordering of the columns.
This example creates an FileListElement object with a renderer:
```
   // Create a FileListElement.
  FileListElement fileList = new FileListElement(sys, httpservletrequest);
  
  // Set the renderer specific to this servlet, which extends
  // FileListRenderer and overrides applicable methods.
  fileList.setRenderer(new myFileListRenderer(request));
  
```
