Hi,
I’m trying to extract files/folders from directories/subdirectories and put everything in a list. I made it work in Java. Here’s the code snippet i have tried so far.

In Shared tab -
SOURCE

public static void Extract(String directoryName)
{ 
try{
File directory = new File(directoryName); 

//get all the files from a directory
File[] fList = directory.listFiles();

//for (File file : fList)
for (int i = 0; i < fList.length; i++)
{
if (fList[i].isFile()){                
} else if (fList[i].isDirectory())
{
//Extract(file.getAbsolutePath());
dirList[i].add(directory.getAbsolutePath());
i++;
}
}
}

catch(Exception exception)
{
//throw new ServiceException("Internal Server Error - Files names could not be retrieved");
}

}

Code

IDataCursor pipelineCursor = pipeline.getCursor();

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

ArrayList<Object> dirList=new ArrayList<Object>();
Extract(dirPath);

// pipeline
IDataCursor pipelineCursor_1 = pipeline.getCursor();
//String[]    dirList = new String[];
//dirList[] = "dirList";
IDataUtil.put( pipelineCursor_1, "dirList", dirList);
pipelineCursor_1.destroy();

In the source, what im trying to do is, if its a directory im trying to call the same function again. but im not able to get the list of folders in the directories/subdirectories.

Please help me out in this.

Thanks

Try this,

Shared:

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;
}

IS Code:

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);

IDataCursor pipelineCursor_1 = pipeline.getCursor();
IDataUtil.put( pipelineCursor_1, "dirList", output.toArray(new String[output.size()]));

Hey Akshith,
Thank you so much. It is working fine.

Glad could help! You were on right track with the requirement about using recursive function call for directory names.
