Package com.vaadin.copilot.javarewriter

Class JavaRewriterObserver

java.lang.Object

com.vaadin.copilot.javarewriter.JavaRewriterObserver

All Implemented Interfaces:

com.github.javaparser.ast.observer.AstObserver

public class JavaRewriterObserver
extends Object
implements com.github.javaparser.ast.observer.AstObserver

Observer for the JavaRewriter that tracks which parts have been deleted and which nodes have potentially been added or modified.

For deleted code we must store the ranges and not the nodes themselves, as the nodes are no longer part of the AST and we are unable to find the related statements later on.
