Interface RemoteBundle

All Superinterfaces:

java.lang.AutoCloseable

All Known Implementing Classes:

SdkHarnessClient.ActiveBundle

public interface RemoteBundle
extends java.lang.AutoCloseable

A bundle capable of handling input data elements for a bundle descriptor by forwarding them to a remote environment for processing.

When a RemoteBundle is closed, it will block until bundle processing is finished on remote resources, and throw an exception if bundle processing has failed.

Method Summary

Modifier and Type	Method and Description
void	close() Closes this bundle.
java.lang.String	getId() Get an id used to represent this bundle.
java.util.Map<java.lang.String,FnDataReceiver>	getInputReceivers() Get a map of PCollection ids to receivers which consume input elements, forwarding them to the remote environment.

Method Detail

getId

java.lang.String getId()

Get an id used to represent this bundle.

getInputReceivers

java.util.Map<java.lang.String,FnDataReceiver> getInputReceivers()

Get a map of PCollection ids to receivers which consume input elements, forwarding them to the remote environment.

close

void close()
    throws java.lang.Exception

Closes this bundle. This causes the input FnDataReceiver to be closed (future calls to that FnDataReceiver will throw an exception), and causes the RemoteBundle to produce any buffered outputs. The call to close() will block until all of the outputs produced by this bundle have been received.
