From d1c3f8eef58b29eb8760eeb1ac03852a2387f927 Mon Sep 17 00:00:00 2001 From: Oren Hurvitz Date: Mon, 31 Mar 2014 11:53:12 +0300 Subject: Added assets service method AssetsExist(), which returns whether the given list of assets exist. This method is used to optimize sending assets with embedded assets: e.g., when a Hypergrid visitor takes an item into the inventory. --- .../Server/Handlers/Asset/AssetServerConnector.cs | 3 +- .../Server/Handlers/Asset/AssetServerGetHandler.cs | 74 +++++++++++++------- .../Server/Handlers/Asset/AssetsExistHandler.cs | 80 ++++++++++++++++++++++ 3 files changed, 131 insertions(+), 26 deletions(-) create mode 100644 OpenSim/Server/Handlers/Asset/AssetsExistHandler.cs (limited to 'OpenSim/Server/Handlers/Asset') diff --git a/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs b/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs index cc4325a..9b86986 100644 --- a/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs +++ b/OpenSim/Server/Handlers/Asset/AssetServerConnector.cs @@ -86,6 +86,7 @@ namespace OpenSim.Server.Handlers.Asset server.AddStreamHandler(new AssetServerGetHandler(m_AssetService));
