org.epics.archiverappliance.retrieval.client.RawDataRetrievalAsEventStream

All Implemented Interfaces:

DataRetrieval

public class RawDataRetrievalAsEventStream
extends Object
implements DataRetrieval

Client side class for retrieving data from the appliance archiver using the PB over HTTP protocol. This is mostly used by the unit tests where the ability to treat retrieval results as event streams is veru useful. Java clients should use the pbrawclient which is a lightweight implementation of the same.
