  org.jactr.core.module.retrieval.buffer.RetrievalRequestDelegate

All Implemented Interfaces:

IRequestDelegate

public class RetrievalRequestDelegate
extends java.lang.Object
implements IRequestDelegate

request handler for the retrieval buffer. If indexed retrievals are enabled, then ChunkRequests are directly inserted into the buffer. Otherwise, all chunk requests are expanded into ChunkTypeRequests. All ChunkTypeRequests are then used to start the retrieval operation.
