Crate java_class_parser

Provides mechanisms to parse and then inspect java class files. Java classes have very specific formats that can be parsed. However, because the format relies on constantly referring back to a constant pool, information can be hard to actually parse. This library provides easier mechanisms for digesting this info.

There are three main entrance points to the api: parse_file, parse_bytes, and JavaClassParser

Example

If you want to inspect many classes, it may be better to create the parser using a classpath, then finding classes by their fully qualified path.

let mut parser = JavaClassParser::new("classes.jar");
let class1 = parser.find("com.example.TestClass").expect("couldn't find class");
let class2 = parser.find("com.example.OtherTestClass").expect("couldn't find class");
