getIndexOfComment

private int getIndexOfComment(Comment oldValue,
                              NodeText nodeText)

findChildTextElementForComment

private java.util.List<ChildTextElement> findChildTextElementForComment(Comment oldValue,
                                                                        NodeText nodeText)

findTokenTextElementForComment

private java.util.List<TokenTextElement> findTokenTextElementForComment(Comment oldValue,
                                                                        NodeText nodeText)

isEqualRange

private boolean isEqualRange(java.util.Optional<Range> range1,
                             java.util.Optional<Range> range2)

fixIndentOfMovedNode

private void fixIndentOfMovedNode(NodeText nodeText,
                                  int index)

This method inserts new space tokens at the given index. If a new comment is added to the node at the position of index, the new comment and the node will have the same indent.

Parameters:

nodeText - The text of the node

index - The position where a new comment will be added to

concreteListChange

public void concreteListChange(NodeList changedList,
                               AstObserver.ListChangeType type,
                               int index,
                               Node nodeAddedOrRemoved)

Overrides:
