|---|
| 30 | |
|---|
| 31 | The changes are "atomic" - if any changes can't be applied, |
|---|
| 32 | none of them can be (tracked by the m_valid flag). |
|---|
| 33 | Similarly, attempts to add the changes from a rich_location flagged |
|---|
| 34 | as containing invalid changes mean that the whole of the edit_context |
|---|
| 35 | is flagged as invalid. |
|---|
| 36 | |
|---|
| 37 | A complication here is that fix-its are expressed relative to coordinates |
|---|
| 38 | in the files when they were parsed, before any changes have been made, and |
|---|
| 39 | so if there's more that one fix-it to be applied, we have to adjust |
|---|
| 40 | later fix-its to allow for the changes made by earlier ones. This |
|---|
| 41 | is done by the various "get_effective_column" methods. */ |
