From 2a018cfa49e0a85d2984f6daf6ee3c3372bdafda Mon Sep 17 00:00:00 2001 From: madmaxoft Date: Tue, 21 Jan 2014 22:59:08 +0100 Subject: Implemented cPluginManager:CallPlugin() API. This function supersedes cPlugin:Call(), is safer to use in regards to multithreading and once again removes the need for the cPlugin class being exported at all. --- src/Bindings/PluginLua.h | 42 ++++++++++++++++++++++++++---------------- 1 file changed, 26 insertions(+), 16 deletions(-) (limited to 'src/Bindings/PluginLua.h') diff --git a/src/Bindings/PluginLua.h b/src/Bindings/PluginLua.h index c01f5ca89..c13f31424 100644 --- a/src/Bindings/PluginLua.h +++ b/src/Bindings/PluginLua.h @@ -105,7 +105,7 @@ public: virtual void ClearConsoleCommands(void) override; - /// Returns true if the plugin contains the function for the specified hook type, using the old-style registration (#121) + /** Returns true if the plugin contains the function for the specified hook type, using the old-style registration (#121) */ bool CanAddOldStyleHook(int a_HookType); // cWebPlugin override @@ -115,26 +115,26 @@ public: virtual AString HandleWebRequest(const HTTPRequest * a_Request ) override; bool AddWebTab(const AString & a_Title, lua_State * a_LuaState, int a_FunctionReference); // >> EXPORTED IN MANUALBINDINGS << - /// Binds the command to call the function specified by a Lua function reference.
