java.lang.Object

org.dcache.xrootd.tpc.protocol.messages.AbstractXrootdOutboundRequest

All Implemented Interfaces:

XrootdOutboundRequest

Direct Known Subclasses:

public abstract class AbstractXrootdOutboundRequest
extends Object
implements XrootdOutboundRequest

Supports outgoing client requests to the source server in third-party copies.

According to protocol, all client requests must have the following packet structure:

kXR_char	streamid[2]
kXR_unt16	requestid
kXR_char	parms[16]
kXR_int32	dlen
kXR_char	data[dlen]

For the purposes of the third-party-client, none of these make use of the data or data length fields.
