List files and directories recursively

This java service will list all the files and the files in the sub-directories with full path names.

IDataCursor pipelineCursor = pipeline.getCursor();

String    dirPath = IDataUtil.getString( pipelineCursor, "dirPath" );

pipelineCursor.destroy();

         

List<String> output=new ArrayList<String>();

         

List<String> tempPlaceHolder=new ArrayList<String>();

output=extract(dirPath,tempPlaceHolder);

  

IDataUtil.put( pipelineCursor, "dirList", output.toArray(new String[output.size()]));

pipelineCursor.destroy();

Shared Code:

public static List<String> extract(String directoryName, List<String> outFiles){

    
File directory=new File(directoryName);
File[] fileList=directory.listFiles();

String outFileName;
for(int i=0;i<fileList.length;i++){
 if(fileList[i].isFile()){
 outFileName=fileList[i].toString();
 outFiles.add(outFileName);
        }
 else{

      outFileName=fileList[i].toString();
      outFiles.add(outFileName);
      extract(outFileName,outFiles);               

     }           
    }

return outFiles;
