    • concretePropertyChange

      public void concretePropertyChange(Node observedNode, ObservableProperty property, Object oldValue, Object newValue)
      Overrides:
      concretePropertyChange in class PropagatingAstObserver

    • isCompleteLine

      private boolean isCompleteLine(List<TextElement> elements, int index)

    • removeAllExtraCharacters

      private void removeAllExtraCharacters(List<TextElement> elements, int index)

    • removeAllExtraCharactersBeforePosition

      private void removeAllExtraCharactersBeforePosition(ListIterator<TextElement> iterator)

    • removeAllExtraCharactersStartingFrom

      private void removeAllExtraCharactersStartingFrom(ListIterator<TextElement> iterator)

    • convertMarkdownCommentContentToTokens

      private List<TokenTextElement> convertMarkdownCommentContentToTokens(MarkdownComment comment)
      Comments must be converted to TokenTextElements that the LPP can work with. For the other comments this is simple since there is a TokenType corresponding to them. A TokenTextElement can just be created from the header, footer, and content of the comment. This is not the case for MarkdownComments, however, since a MarkdownComment is made up of a sequence of whitespace and line comment tokens. This sequence is therefore manually reconstructed from the comment content.

    • makeCommentTokens

      private List<TokenTextElement> makeCommentTokens(Comment newComment)

    • getIndexAndCountOfCommentTokens

      private Pair<Integer,Integer> getIndexAndCountOfCommentTokens(Comment oldValue, NodeText nodeText)

    • findChildTextElementForComment

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

    • selectMatchingChildElements

      private List<ChildTextElement> selectMatchingChildElements(Comment oldValue, NodeText nodeText)

    • isSameComment

      private boolean isSameComment(Comment childValue, Comment oldValue)

    • findTokenTextElementForComment

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

    • fixIndentOfAddedNode

      private void fixIndentOfAddedNode(NodeText nodeText, int index)
      This method inserts new space tokens at the given index. If a new comment is added to the token list at the position following index, the new comment and the node will have the same indent.
      Parameters:
      nodeText - The text of the node
      index - The position at which the analysis should start
