SECRlpEncode

This package is used for SEC blockchain rlp encoding.


new SECRlpEncode(config)

new SECRlpEncode(config) Constructs a rlp encode class.

ParamTypeDescription
configTBDTBD, will be implemented in the future

Example

const RLP = require('encode.js')

const rlp = new RLP()

SECRlpEncode.encode(input, buffer, offset) ⇒ Buffer

Returns input in RLP encoded format

ParamTypeDescription
input{Buffer, String, Integer, Array}Input data for RLP encode
buffer{Buffer}Input buffer which is in RLP encoded format
offset{Buffer}Buffer offset position

SECRlpEncode.decode(input, start, end) ⇒ Array

RLP decode for input data

ParamTypeDescription
input{Buffer, String, Integer, Array}Input should be in RLP encoded structure
start{Integer}"input" data array starting index
end{Integer}"input" data array ending index

SECRlpEncode.getLength(input) ⇒ Number

Returns input's length according to the first several indication bytes

ParamTypeDescription
input{Buffer, String, Integer, Array}Input should be in RLP encoded data, or the returned length is wrong

中文简介:

本库函数用于SEC区块链的RLP编码 RLP编码用于存储和传输数据,处理数据则用.json格式文件 json文件由RLP编码过以后,由于json文件的键值被去掉了,仅保留内容,因此剩下了大量的空间

主要的函数: 1. RLP编码: encode(input, buffer, offset) => Buffer 输入"input"可以是{Buffer,String,Integer,Array},RLP编码仅对两种数据结构进行处理:列表及字符串 Nodejs中Array即为列表,其他类型{Buffer,String,Integer}作为字符串处理 该函数的输出结果为RLP编码后的input,类型为Buffer

  1. RLP解码:decode(input, start, end) => Array 输入"input"可以是{Buffer,String,Integer,Array},无论哪种类型,都会被先转换为Buffer类型再进行处理 作用与encode相反,将RLP格式的数据进行解码, 输出为Array类型

  2. 获取长度函数: getLength(input) => Number input为经过RLP编码后的数据 函数根据前几个字节的值获取整个input数据的长度
