|
GetSourceSpans() | Gets all the source spans for the projection snapshot. |
|
GetSourceSpans(Int32, Int32) | Gets a read-only collection of source snapshot spans starting at the specified location of the span. |

|
MapFromSourceSnapshot(SnapshotSpan) | Maps a snapshot span of a source buffer to a list of spans of the projection snapshot. |

Remarks
This snapshot contains projections of other text snapshots, described by a list of tracking spans from those buffers. Every modification of a projection buffer or one of its source buffers generates a new projection snapshot.
