Method Detail

importData

String[] importData(String reference,
                  InputStream data,
                  String encodingKey,
                  Map<String,Object> params)

Request that an import stream be turned into real data related to the entities in this provider and associated with a specific entity (this will probably not be an entity in this provider)

Parameters:

reference - a globally unique reference to an entity, this is the entity that the imported data should be associated with (e.g. a reference to a site object or user)

data - a stream of data from the archiver/importer, this should match a previous export stream exactly (or at least very closely in order for the importer to be able to understand it)

encodingKey - a string representing the encoding used and possibly other info like a version, this should be the string sent with the export

params - (optional) incoming set of parameters which may be used to send data specific to this request, may be null

Returns:

the array of all entity references which were created from the import OR empty if none created

Throws:

IllegalArgumentException - if any arguments are invalid or missing

IllegalStateException - if a failure occurs with the import (message should be as descriptive as possible)
