-- I think the cause is the table.concat treat every item in ByteArray._buf as a general string, not a char. -- So, I use lpack repackage the ByteArray._buf, theretofore, I must convert them to a byte number. function ByteArray:getPack(__offset, __length) __offset = __offset...
差别及byte[ ]和string转换 先看Byte,是一类:public final class ByteTheByteclass wraps a value of primitive typebytein an object. An object of Bytecontains a single field whose type isbyte.In addition, this class provides several methods for converting abyteto aStringand aStringto abyte,...

type(type(x)) --> string 关于userdata 这种类型可以把任意C语言数据保存在Lua语言变量中,这个类型被用来被用来表示由应用或C语言编写的库所创建的新类型 ,比如标准I/O库使用用户数据来表示打开的文件 关于boolean ,false 和 nil 以外的所有其他值都视为真。没错。你没有看错。在条件检测中 Lua 语言把零和空...
在两种情况下,buffer是包含字节的Lua字符串。如果需要从Lua访问单个字节值,string.byte将是您的好朋友。 要指定打包数据的字节顺序,请将格式从"l"更改为"<l"(小端)或">l"(大端)。 该struct模块是用C实现的,必须在平台上编译为DLL或等效项后才能被Lua使用。话虽如此,它包含在Lua for Windows预装程序包中,这...
