Reflection type Modifier class

Modifier class

Modifier used to represent the weight value of each modifier, expressed in hexadecimal

16 rpm 10-ary calculation rules:

16进制数转10进制数的原理：1000=1X16^3（16的3次方）+0X16^2（16的2次方）+0X16（16的1次方）+0X1（16的0次方）=4096。

A = 10， B = 11,，C =12，D=13，E=14，F= 15。

FFF=15*(16^2) + 15*(16^1) + 15*(16^0)  = 4095。
