| |
| The changes are "atomic" - if any changes can't be applied, |
| none of them can be (tracked by the m_valid flag). |
| Similarly, attempts to add the changes from a rich_location flagged |
| as containing invalid changes mean that the whole of the edit_context |
| is flagged as invalid. |
| |
| A complication here is that fix-its are expressed relative to coordinates |
| in the files when they were parsed, before any changes have been made, and |
| so if there's more that one fix-it to be applied, we have to adjust |
| later fix-its to allow for the changes made by earlier ones. This |
| is done by the various "get_effective_column" methods. */ |
