codegraph-java

Java parser for CodeGraph - extracts code entities and relationships from Java source files.

Features

• Parse Java source files (.java)
• Extract classes, interfaces, enums, and records
• Extract methods and constructors
• Track relationships (calls, imports, inheritance, implementations)
• Support for Java packages and imports
• Full integration with codegraph-parser-api

Usage

use codegraph_java::JavaParser;
use codegraph_parser_api::CodeParser;
use codegraph::CodeGraph;
use std::path::Path;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut graph = CodeGraph::in_memory()?;
    let parser = JavaParser::new();

    let file_info = parser.parse_file(Path::new("Main.java"), &mut graph)?;
    println!("Parsed {} functions", file_info.functions.len());
    println!("Parsed {} classes", file_info.classes.len());
    Ok(())
}
