jQAssistant Scanner for Method Parameter

Question

I am currently struggeling with the development of an custom jQAssistant Scanner.

Background:

public class MyEntityDAOImpl {

public MyEntity getMyEntity(){
final TypedQuery<MyEntity> query = getEntityManager()
                .createNamedQuery(MyEntity.QUERY_NAME, MyEntity.class);
return getResult(query);
}

}

A Method getMyEntity() is using JPA Named Queries to get a matching result from the database. The query name is as static final String constant of the MyEntity class.

Task:

In order to perfrom quality quecks in our project, I would need to know which named query is called by the getMyEntity() method. I would like to develop a custom scanner to extend my Neo4J DB to look something like this:

I would use RegEx matching to get the String literal "MyEntity.QUERY_NAME". Ideally I would even like to get the String value of this variable, but the literal should suffice. My Question is, know how to attach the new node to the existing (:Java:PublicMethod) one. Do I need to extend the JavaScanner?

I am just starting to work with jQAssistant and any help is greatly appreciated!

Best, Patrick
