A difference viewer is a container for viewing an IDifferenceBuffer in an inline or side-by-side mode. It keeps the scroll state of the different views in sync, and provides helpers for scrolling to differences and matches in all views.
Used to retrieve an ITextDifferencingService for a given content type. These services may be provided by extenders and may return differences that more closely match the semantics of the given content type, instead of simple textual differencing.
This service has methods that compute differences over strings, snapshots, and spans. Differences are computed according to the specified StringDifferenceTypes, starting with the most general type (line is more general than word, and word is more general than character). This service is meant to be provided by extenders to override diff behavior by content type, thus allowing more control over the differences produced and how they align semantically (based upon the given language/content type).
A custom transform for text snapshot lines, to allow clients of IDifferenceBuffer to modify lines before performing any comparison.line: The original snapshot line that this transform is being asked to operate on.</currentText: The current text of the line, which may differ from GetText" if an earlier transform has already processed the line.Returns the new line text to use for the line.
