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. */ | |
