LuaCallbacks.h contains main part of the wrapper. It contains templated meethods that are called from Lua, methods binded to Lua metamethods like __gc, __index, __newindex, __tostring etc. and constructors for Lua classes.LuaFunctionWrapper.h contains a static class wrapping Lua methods ...

no_white() - Checks if a string contains no white spaces. number() - Checks if a value is a number. string() - Checks if a value is a string. type(t) - Checks if a value is of type t. optional(t) - If value isnilit would be accepted. If it's notnilit would be processed...
This topic contains important information on necessary precautions. We recommend that you read this topic carefully before proceeding. Tair (Redis OSS-compatible) instances support Lua commands. Lua scripts can be used to efficiently process compare-and-set (CAS) commands. This improves the performance...

Get<int>("a"); luaenv.Global.Get<string>("b") luaenv.Global.Get<bool>("c") 所以要了解C#调用Lua,就先从LuaTable的TValue Get<TValue>(string key)开始。 下面的Get方法比较简单,就是把即将要访问的table和key先压入栈,并取出value放在栈上,并初步判断合法性。
Thelua_getfield()function introduces the idea of anindex, which is an integer indicating a position in Lua’s stack. Suppose that the Lua stack currently contains these values, with the bottom of the stack on the left: [3, nil, false, {key = 'value'}, 42] ...
Returns true when the given Lua table contains neither non-nil array elements nor non-nil key-value pairs, or false otherwise.This API can be JIT compiled.Usage:local isempty = require "table.isempty" print(isempty({})) -- true print(isempty({nil, dog = nil})) -- true print(is...
