                                                             throws org.json.JSONException

Attempts to retrieve and convert a JSON array of NodeRefs from the given JSON object. If the nodeRefs property is not present a WebScriptException is thrown.

Parameters:

json - JSONObject

Returns:

Array of NodeRef objects

Throws:

org.json.JSONException

createACP

protected File createACP(ExporterCrawlerParameters params,
                         String extension,
                         boolean keepFolderStructure)

Returns an ACP file containing the nodes represented by the given list of NodeRefs.

Parameters:

params - The parameters for the ACP exporter
