Class InboundReadResponse

java.lang.Object

org.dcache.xrootd.tpc.protocol.messages.AbstractXrootdInboundResponse

org.dcache.xrootd.tpc.protocol.messages.InboundReadResponse

All Implemented Interfaces:

io.netty.util.ReferenceCounted, XrootdInboundResponse, ByteBuffersProvider

public class InboundReadResponse
extends AbstractXrootdInboundResponse
implements ByteBuffersProvider

Response from third-party source server.

The implementation of the ByteBuffersProvider interface assimilates this response with an incoming client write request.

The third-party client in effect acts as a pipe between the remote read of the file and the local write. Merging that functionality into a single object allows us to bypass an extra buffer copy.
