#for(x in model.prototypes) { @ColumnWidth(20) private ${x.propertyType!} ${x.propertyName!}; #} 这是什么语法

这是一种模板语法,通常用于代码生成器或者模板引擎中。它的具体语法可能因不同的实现而略有不同,但通常具有以下特征:
以#开头的语句表示控制语句,如if语句、for循环等;
以$开头的语句表示变量引用,可以引用上下文中的变量;
以!表示默认值,当变量不存在时可以使用默认值来代替;
语句通常以}结尾,以便与其他语句区分开来;
在模板引擎中,通常会将模板和数据混合在一起,然后通过模板引擎将其渲染为最终的输出。在代码生成器中,通常会将模板和元数据混合在一起,然后通过代码生成器将其转换为最终的源代码。

在你提供的代码中,for循环语句遍历了model.prototypes数组中的元素,并将每个元素中的propertyType和propertyName属性插入到模板中。这样,代码生成器就可以根据模板和元数据生成相应的源代码了。
