      tokenHighlightsChanged in interface ClangHighlightListener

    • tokenRenamed

      public void tokenRenamed(ClangToken token, String newName)
      This function is used to alert the panel that a token was renamed. If the token being renamed had a middle-mouse or secondary highlight, we must re-apply the highlights to the new token.

      This is not needed for highlighter service highlights, since they get called again to re-apply highlights. It is up to that highlighter to determine if highlighting still applies to the new token name. Alternatively, for secondary highlights, we know the user chose the highlight based upon name. Thus, when the name changes, we need to take action to update the secondary highlight.

      Parameters:
      token - the token being renamed
      newName - the new name of the token
