From 4ef02bc1b6cf5e044d2cf57725eac1a4ccd7580d Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Fri, 18 Feb 2011 10:56:26 -0500 Subject: Introduce and use new sendReply() function for LLEventAPI methods. Each LLEventAPI method that generates a reply needs to extract the name of the reply LLEventPump from the request, typically from a ["reply"] key, copy the ["reqid"] value from request to reply, locate the reply LLEventPump and send the enriched reply object. Encapsulate in sendReply() function before we proliferate doing all that by hand too many more times. --- indra/llcommon/llevents.cpp | 13 +++++++++++++ indra/llcommon/llevents.h | 14 ++++++++++++++ indra/llui/llfloaterreglistener.cpp | 12 ++++-------- indra/newview/llsidetraylistener.cpp | 15 +++++---------- indra/newview/llviewerwindowlistener.cpp | 5 +---- 5 files changed, 37 insertions(+), 22 deletions(-) (limited to 'indra') diff --git a/indra/llcommon/llevents.cpp b/indra/llcommon/llevents.cpp index 97e2bdeb57..ff03506e84 100644 --- a/indra/llcommon/llevents.cpp +++ b/indra/llcommon/llevents.cpp @@ -588,3 +588,16 @@ void LLReqID::stamp(LLSD& response) const } response["reqid"] = mReqid; } + +bool sendReply(const LLSD& reply, const LLSD& request, const std::string& replyKey) +{ + // Copy 'reply' to modify it. + LLSD newreply(reply); + // Get the ["reqid"] element from request + LLReqID reqID(request); + // and copy it to 'newreply'. + reqID.stamp(newreply); + // Send reply on LLEventPump named in request[replyKey].
