Java Source Code AST: Difference between revisions

Latest revision as of 04:36, 8 May 2024

Context:
- It can be generated by a Java Source Code AST Decoder.
- …
Example(s):
- a Java 15 Eclipse AST.
- a Labeled Java AST, such as https://code2seq.org.
- …
Counter-Example(s):
- Python Source Code AST.
- Scala Source Code AST.
See: Java Parser, JavaParser.

Input: Java Source Code	Output: AST

"JavaParser: Java Code Generation."
- QUOTE: ... In its simplest form, the JavaParser library allows you to interact with Java source code as a Java object representation in a Java environment. More formally, we refer to this object representation as an Abstract Syntax Tree (AST). Also, it has the ability to manipulate the underlying structure of the source code. This can then be written to a file, providing developers with the facility to build their own code generating software. ...

- QUOTE: ... This tutorial ... also explains the Abstract Syntax Tree (AST) and the Java model in Eclipse. ...
  The AST is a detailed tree representation of the Java source code. The AST defines an API to modify, create, read and delete source code. The main package for the AST is the org.eclipse.jdt.core.dom package and is located in the org.eclipse.jdt.core plug-in. Each Java source element is represented as a subclass of the ASTNode class. Each specific AST node provides specific information about the object it represents. …

- QUOTE: As far as I know, the only way to parse Java source-code into an AST (Abstract Syntax Tree) is to use the Java Compiler Tree API: com.sun.source.tree
  - I have two questions:
    1. What JDKs support com.sun.source.tree?
    2. Is there a portable replacement that works for all JDKs?
