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