javalang-compiler: Symbol and type resolution for Javalang

Build Status Coverage Status

Java 8 semantic analysis for the javalang project. Therefore, the Java 8 AST is enriched with data calculated during the semantic analysis. Mainly, the calculated data is:

  • Symbols data types: In other words, what are the Java runtime classes, fields and methods that a given type or expression is referencing. For example, if the AST contains a MethodCallExpr node, the method getSymbolData() of this node returns the java.lang.Method that this node is referencing.

  • Definitions and usages: For those nodes that are subclass of SymbolDefinition (e.g declarations), the nodes contain which external references(getBodyReferences()) they have and which nodes reference them inside the same compilation unit (getUsages()).

Usage

If you are interested in creating a new walkmod plugin for Java code that requires this kind of information, you must add the following steps:

  1. Add the following dependency in your project.

<dependency>
    <groupId>org.walkmod</groupId>
    <artifactId>javalang-compiler</artifactId>
    <version>{last-version}</version>
</dependency>

  1. Annotate your code transformations (visitors) with the @RequiresSemanticAnalysis annotation. Walkmod (specifically the walkmod-javalang-plugin), will automatically run the org.walkmod.javalang.compiler.symbols.SymbolVisitorAdapter to enrich the nodes.

  2. Add a walkmod plugin in your walkmod.xml file that resolves your classpath and compiles your code (e.g walkmod-maven-plugin)
