Lua学习教程之 可变參数数据打包与解包

利用table的pack与unpack进行数据打包与解包。測试代码例如以下:

print("Test table.pack()----------------");function printTable ( t )if type(t) == "table" thenfor k,v in pairs(t) doprintTable(v);endelseprint(t);end
endlocal packData =function( ... )local arg = table.pack(...);--arg.n 得到可变部分的參数的个数-- print("arg.n:", arg.n)for k,v in pairs(arg) doprint("----------------");print(k,v);printTable(v);print("----------------");endreturn arg;
endpackData({type=100,param={"param1", "param2", "param3"}});
-- packData("param1", "param2", "param3","param4","param5");print("\nTest table.unpack()----------------");
local data = {"AA", "BB", "CC", "DD"} 
print(table.unpack(data))
print(table.unpack(data, 2))
print(table.unpack(data, 2, 3))
