Multiple returned values In Lua, a function mayreturnany number of values. tolua usesthisfeature to simulate values passed by reference. If a function parameterisspecifiedasa pointer to or reference of a basic type or a pointer to or reference of a pointer to an user defined type, tolua acce...
首先来看这个注释:Lua can return multiple values, for this reason DoString return a array of objects,就是直接调用DoString方法的时候返回的结果是一个object[]类型,所以这里需要取结果的时候要取用第一个 图三DoString生成结果 2.2 注册Lua Function
// Call function with two arguments that returns an int // The type parameter can be one of int, lua_Number, std::string, // bool, or unsigned int int result = state["add"](5, 2); assert(result == 7); // Call function that returns multiple values ...
Lua supports functions that return multiple values at once. A C++ function can do so by returning a tuple. In this example we return at the same time an int and a string. Tuples are only supported when returning as a return value for a function. Attempting to write or read a tuple wi...
> obj = setmetatable({},{ __newindex = function(t,k,v) print(v) end }) > extend(obj,{1,2,3}) 1 2 3 To insert multiple values into a position within an array, useinsertvalues. It works liketable.insert, except that the third argument is an array of values. If you do want...
在Lua中函数都是function类型的对象可被比较 可赋值给一个变量 可传递给函数 可从函数中返回 可作为table表中的键函数定义Lua使用关键字function定义函数function fn(arg) -- function body... end 函数定义的语法会定义一个全局函数,名为fn,全局函数本质上是函数类型的值赋给全局变量。
The following function returns the SHA1 value of strin in the string format. def calcSha1(strin): sha1_obj = hashlib.sha1() sha1_obj.update(strin.encode('utf-8')) sha1_val = sha1_obj.hexdigest() return sha1_val class MyRedis(redis.Redis): def __init__(self, host="...
