JavaParser v3.1.0-beta.1 Release Notes

  • This version is a beta because there are a lot of new features that may still change.

    This version needs a minor version increase because of a backwards compatability issue:

    • 719 getJavadoc, getJavadocComment and getComment could return null. Our promise was to return Optional, so that is what they do now.

    🆕 New:

    • 658 718 736 737 we have created a metamodel. It gives information about the structure of the various AST nodes, as if you are introspecting them. 📜 You can find it in javaparser-metamodel, the main class is JavaParserMetaModel
    • 353 365 visitors are no longer hand made, they are now generated from the metamodel. This should make them 100% reliable. 👯 Affected visitors are: GenericVisitorAdapter, EqualsVisitor, VoidVisitorAdapter, VoidVisitor, GenericVisitor, HashCodeVisitor, CloneVisitor.

    📜 If you want to generate your own visitors, you can use the VisitorGenerator class from javaparser-core-generators

    📜 If you want to reuse the code generation utilities, look at module javaparser-generator-utils - there is a very useful SourceRoot class in there that takes away a lot of file management troubles.

    • 538 735 TreeStructureVisitor has been added, which should be considered beta.
    • 🛠 220 733 717 749 745 750 743 748 666 732 746 734 733 smaller improvements and fixes
