callgraph's Introduction

Call Graph

Introduction

The project aims to generate a call graph for Java JAR files or .class files using ASM. The call graph includes every call path from source to target, providing researchers with a lightweight tool to obtain a project's call graph. The project's call graph achieves the precision of Class Hierarchy Analysis (CHA).

How to Use

Install the Project

mvn clean package install

Import the Project

Firstly, import the project into your Java project using Maven. Add the following dependency to your pom.xml file:

<dependency>
    <groupId>xmu.lab</groupId>
    <artifactId>callGraph</artifactId>
    <version>0.0.2-SNAPSHOT</version>
</dependency>

Execute Call Graph Analysis

In your Java code, call the following method to perform call graph analysis:

        CallGraph callGraph = CallGraph.getInstance();
        ArrayList<String> jarPaths = new ArrayList<>();
        jarPaths.add(directoryUrl.getPath());
        callGraph.addPaths(jarPaths);
        callGraph.create();
        Set<MethodCall> methodCalls = callGraph.getMethodCalls();

Features

ASM Integration: Utilizes ASM to parse Java bytecode for accurate call graph generation.
CHA: Achieves the precision of Class Hierarchy Analysis for a comprehensive view of the project's dependencies.
Class and JAR Analysis: Supports the analysis of individual classes or entire JAR packages.

TODO

Optimization: Explore opportunities to enhance the performance and accuracy of call graph generation.
Documentation: Expand and improve project documentation for better usability.
