2.5.7 –Table Constructors Table constructors are expressions that create tables. Every time a constructor is evaluated, a new table is created. A constructor can be used to create an empty table or to create a table and initialize some of its fields. The general syntax for constructors is...
表格在整个Lua语言的数据结构中占有重要地位,正如Lua的作者所说: Tables are the main — in fact, the only — data-structuring mechanism in Lua.Table是Lua的主要(事实上,也是唯一的)数据结构。 数组变量的初始化有三种形式:最为常见的就是使用逗号分开的值;第二种是[index] = value形式的初始化,这种形式...
tables的实现被分成了两个部分: 核心由ltable.c完成,提供了table的基本存取方法, 外部table库(ltablib.c)提供了辅助操作接口(concat, foreach, foreachi, getn, maxn, insert, remove, setn, sort). ltable.c table的主要代码在这里 lobject.h lua的基础对象的定义,包括table 直接上 一.table的结构定义:...
Lua学习笔记_Table 表 表的构造式就是创建并初始化表的表达式。它是Lua中非常独特的特性,也是Lua中最有用且灵活的机制之一。 Constructors are expressions that create and initialize tables. They are a distinctive feature of Lua and one of its most useful and versatile mechanisms. 怎么创建一个表 最简单...
As tables are associative, we can use string based keys as well as shown below.main.luaOpen Compiler -- dictionary of days days ={["Sun"] = "Sunday", ["Mon"]="Monday", ["Tue"]="Tuesday",["Wed"]="Wednesday", ["Thu"]="Thursday", ["Fri"]="Friday", ["Sat"]="Saturday"} ...
字符串表,关联数组表,文件列表 所有的这些在 table.c 中定义的这些数组可以认为是 Lua 的全局注册表空间,Lua 的环境。 函数分析 /* ** Given a name, search it at symbol table and return its index. If not ** found, allocate at end of table, checking oveflow and return its index. ...
[3]="blue",} 同php一样,table后面放分号不影响正确性。 Such flexibility makes it easier to write programs that generate Lua tables, because they do not need to handle the last element as a special case。 Finally, you can always use a semicolon instead of a comma in a constructor. We ...
