FileAnalyzer
A universal binary data parser that can freely expand the type. 一个通用的二进制数据解析器, 可以自由扩展类型.
The currently supported parsing type is JavaClass 目前已支持的解析类型为 JavaClass.
Subsequent preparations for adding types: PE files, IP datagrams, etc. 后续准备添加的类型: PE文件, IP数据报等
Test Code
let fa = new FileAnalyzer('test.class');
let res = fa.analyze(AnalyzerJava);
console.log(res);
output:
