Java 1-14 Parser and Abstract Syntax Tree for Java, including preview features to Java 13.
I'm speculating that it shouldn't be used, and the variables should have the type now?
I'm also trying to figure out what the equivalent of https://www.javadoc.io/static/com.github.javaparser/javaparser-core/2.5.1/com/github/javaparser/ast/body/MultiTypeParameter.html is
maybe just UnionType
We have a project that's using an older version of javaparser (3.5.9). I want to upgrade it to the latest, which normally just involves reading release notes sequentially and updating code as needed. But I can't find the release notes! I found https://github.com/javaparser/javaparser/releases, which seems to be autogenerated, and doesn't have any useful documentation. Where should I be looking?
Finally found it: https://github.com/javaparser/javaparser/blob/master/changelog.md. It would be helpful for the main javaparser page to link to the changelog.
trying to figure out what to do with Parameters to determine if the type is an array since
getId is gone
object ScalaModifier {
object Keyword {
val LAZY = Modifier.Keyword.valueOf("lazy")
val OBJECT = Modifier.Keyword.valueOf("object")
val IMPLICIT = Modifier.Keyword.valueOf("implicit")
val VAL = Modifier.Keyword.valueOf("val")
val VAR = Modifier.Keyword.valueOf("var")
// Dummy Keywords used to keep state
val PROPERTY = Modifier.Keyword.valueOf("@@property@@")
val DummyKeywords: Seq[Modifier.Keyword] = Seq(PROPERTY)
}
}
created what I needed that way
I'm guessing
"Array[" * v.getId.getArrayCount + n.getElementType.accept(this, arg) + "]" * v.getId.getArrayCount + is just n.getElementType.accept(this, arg)
```object ScalaModifier {
object Keyword {
val LAZY = Modifier.Keyword.valueOf("lazy")
val OBJECT = Modifier.Keyword.valueOf("object")
val IMPLICIT = Modifier.Keyword.valueOf("implicit")
val VAL = Modifier.Keyword.valueOf("val")
val VAR = Modifier.Keyword.valueOf("var")
// Dummy Keywords used to keep state
val PROPERTY = Modifier.Keyword.valueOf("@@property@@")
val DummyKeywords: Seq[Modifier.Keyword] = Seq(PROPERTY) }
}```
For something like https://www.javadoc.io/static/com.github.javaparser/javaparser-core/3.16.1/com/github/javaparser/ast/stmt/ForEachStmt.html is it safe to pass a
null as the scope?
considering there are so many
.getFoo() that return Optional it would be kind of nice to have constructors that also take the Optional values
what's the R suppose to be? just Node?
Hello, i'm new to JavaParser !
I'm developping a maven plugin that scans the code to know which Spring Rest-Endpoint trigger an external http request to other micro-services, we are using a custom class that makes http request called Accessible, the goal is the to be able to draw a complete graph of dependencies between multiple endpoints of microservices,
The problem that i have now, is the to know to trace the function calls flow, from the method of the controller to the Accessible-call to make an external http request, the program flow might go trough multiple function calls successively
Is there a way to do that with java parser, or i will have to manually construct a function call graph ?
Thank you all !

I found a similar question on Github, take a look: javaparser/javaparser#1239
maybe this helps you too, https://javaparser.org/setting-up-for-analysing-a-whole-project
I'll take a look
Thank you !!
scala> com.mysema.scalagen.ScalaModifier
java.lang.IllegalArgumentException: No enum constant com.github.javaparser.ast.Modifier.Keyword.lazy
at java.lang.Enum.valueOf(Enum.java:238)
at com.github.javaparser.ast.Modifier$Keyword.valueOf(Modifier.java:92)@matozoid is there any way for me to create my own keywords? or is this the
DataKey you mentioned?
@Lucasgontijo0 Hello,
I was able to construct the method call tree manually, by creating indexing all methods in a list and linking everything with a recursive function, it works but i think i'll go for your solution since it might bug if there's overloading of functions ...
beside this, i have a new question that concern the symbol resolving too :
Accessor a = new Accessor( a, b, c);
a.getApiResponseOf(...);
a= new Accessor(d,e,f);
a.getApiResponseOf(...);
I want to get the information about each pair of constructor and method call of getApiResponseOf(...);
I need some MetaData present in the parameters passed to the constructor and also another data in the call function itself,
The problem that i encounter here, is that i don't know how to construct the specific pair, so we can't use the Accessor with a,b,c with the second method call,
Do you have any clues ?
Thank you all !
case b: BlockStmt => if (b.getStatements != null && b.getStatements.size == 1) {
val foo: Node = b.getStatements.get(0)
if (foo.isInstanceOf[NameExpr]) {
throw new IllegalArgumentException(s"wtf foo: $b")NameExpr should be a Statement, right?

Hi @all, how to use lexicalPreservingprinter along with source root ? Sharing the code snippet below, i have used
parserConfiguration.setLexicalPreservationEnabled(true);statement but it does not looks like working, i am not sure how to use sourceRoot.setPrinter() with LexicalPreservingPrinter class
CombinedTypeSolver typeSolver = new CombinedTypeSolver(
new ReflectionTypeSolver(), new JavaParserTypeSolver(codeDir));
ParserConfiguration parserConfiguration = new ParserConfiguration()
.setSymbolResolver(new JavaSymbolSolver(typeSolver));
parserConfiguration.setLexicalPreservationEnabled(true);
// Parse all source files
SourceRoot sourceRoot = new SourceRoot(codeDir.toPath());
sourceRoot.setParserConfiguration(parserConfiguration);
List<ParseResult<CompilationUnit>> parseResults;
try {
parseResults = sourceRoot.tryToParse("");
// Now get all compilation units
compilations = parseResults.stream()
.filter(ParseResult::isSuccessful)
.map(r -> r.getResult().get())
.collect(Collectors.toList());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (int i =0; i < compilations.size(); i++) {
CompilationUnit cuu = compilations.get(i);
LexicalPreservingPrinter.setup(cuu);
}
modifyCode(compilations);
// sourceRoot.setPrinter(new PrettyPrinter(new PrettyPrinterConfiguration().setEndOfLineCharacter("\n"))::print);
sourceRoot.saveAll();
good morning/evening
