transform data from bytes to entityObject

Primary LanguageJava

ByteToEntity

We always encounter such a situation:data from hardware isbyte[],but we need a class in coding. So that we can transform the Object to json or xml and send it to other place such as WEB.

usage

First create a class,Second set a Rule Annotation on the filed.Just like this:

class DianData{
    @Rule(start=0,type= RuleType.UINT8)
    private double Did;

    @Rule(start = 0,type = RuleType.INT32)
    private int Current;

    @Rule(start=0,type = RuleType.FLOAT)
    public float Vers;

    @Rule(start=2,length = 2,type= RuleType.HEX)
    public String Cid;
}

And then

DianData dd = new Converter(new ByteConvertImpl()).bytesToEntity(new DianData(),new byte[]{0x54,0x01,0x01,0x34});

dd is the Object we expect.

remind

1.When the field is not Hex(String),the length of Rule is ignored.Although you set it,it's not useful.
2.If you have another method to get the value.For example the high and low of data is the opposite of that I show.You can implement the ByteConvert interface.And inject the constructor of Converter.

中文简述

我们总是遇到这样的情况：来自硬件的数据是byte []，但是我们在编码中需要一个**class **。 这样我们可以将Object转换为json或xml，并将其发送到其他地方，如WEB。

用法

注意

1.当字段不是Hex（String）时，Rule的长度被忽略。即使你设置了它，也没有用。
2.如果你有另一种方法来转换。例如，数据的高低是与我的相反。你 可以实现ByteConvert接口。并注入Converter的构造函数。
