class CustomClassVisitor extends ClassVisitor {
public constructor() {
super(Opcodes.ASM5);
}

// visit the class
visit(version: number, access: number, name: string, signature: string, superName: string, interfaces: string[]): void {
}

// visit method
public visitMethod(access: number, name: string, desc: string, signature: string, exceptions: string[]) {
return null;
}

// visit field
public visitField(access: number, name: string, desc: string, signature: string, value: any) {
return null;
}
}

const visitor = new CustomClassVisitor();
const classData: Buffer = await fs.readFile("path/to/some.class");
new ClassReader(classData).accept(visitor);
