I am using Javaparser to parse Java source code.
Is there a way to implement a Visitor that can visit the abstract Node class?
I want to visit every Node and print its line number, but I don't want to implement a visit() method for every Node type (AssignExpr, BinaryExpr, IfStmt, etc...) because there are so many types.
A visitor makes sense only to process different types of element. You can instead start from the root (the CompilationUnit) and pass it to your method process:
void process(Node node){
// Do something with the node
for (Node child : node.getChildrenNodes()){
process(child);
}
}
