Method Detail

createAndBind

public static <T> void createAndBind(Integer port,
                                     RemoteCollectorConsumer<T> consumer,
                                     String rmiId)

This factory method creates an instance of the RemoteCollectorImpl and binds it in the local RMI Registry.

Parameters:

port - The port where the local colector is listening.

consumer - The consumer instance.

rmiId - An ID to register the collector in the RMI registry.

collectLocal

public static <T> DataSink<T> collectLocal(DataSet<T> source,
                                           RemoteCollectorConsumer<T> consumer)

Writes a DataSet to a RemoteCollectorConsumer through an RemoteCollector remotely called from the RemoteCollectorOutputFormat.

Returns:

The DataSink that writes the DataSet.

collectLocal

public static <T> void collectLocal(DataSet<T> source,
                                    Collection<T> collection)

Writes a DataSet to a local Collection through an RemoteCollector and a standard RemoteCollectorConsumer implementation remotely called from the RemoteCollectorOutputFormat.

Parameters:

source - the source data set

collection - the local collection
