Retrieving a list of reports for a specific category

Is there a way to retrieve a list of reports for specific category programmatically using the Java SDK?

I started with this earlier message but wasn't able to to find any example of how this would work using the SDK.

Current Code:

// Get a list of available categories
  try {
  query = new String("SELECT * FROM CI_INFOOBJECTS WHERE SI_PARENTID=45");
  logDebug("Checking Categories Folder: " + query);
  infoObjects = (IInfoObjects) infoStore.query(query);

  } catch (SDKException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  }

  if (infoObjects.getResultSize() == 0){
  throw new SAPException("No Categories found");
  }else{
   //Retrieve reports for each category

  for (int i = 0; i < infoObjects.size(); i++) {

  IInfoObject infoObject = (IInfoObject) infoObjects.get(i);

  // process folder
  try {
          //Query for all reports with current category
          // NEED HELP HERE

  } catch (SAPException exception) {
  logError(exception.getMessage());
  }
  }
