Class TpcSourceReadHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

org.dcache.xrootd.tpc.AbstractClientRequestHandler

org.dcache.xrootd.tpc.AbstractClientSourceHandler

org.dcache.xrootd.tpc.TpcSourceReadHandler

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

public abstract class TpcSourceReadHandler
extends AbstractClientSourceHandler

This handler reads until the file is complete, terminating the session thereafter. When complete, it uses the write handler on its client to send a reply to the kXR_sync request received from the initiating client, and calls back to disconnect the third-party client.

Optional checksum verification (done prior to the sync reply) is implemented by subclasses.
