Constructors

Selection(SnapshotPoint, PositionAffinity)	Instantiates a new Selection with a zero-width extent at the provided insertion point.
Selection(SnapshotPoint, SnapshotPoint, SnapshotPoint, PositionAffinity)	Instantiates a new Selection.
Selection(SnapshotPoint, SnapshotPoint)	Instantiates a new Selection with the given anchor and active points, and the insertion point is located at the active point.
Selection(SnapshotSpan, Boolean)	Instantiates a new Selection with the given extent. Anchor and active points are defined by isReversed, and the insertion point is located at the active point.
Selection(VirtualSnapshotPoint, PositionAffinity)	Instantiates a new Selection with a zero-width extent at the provided insertion point.
Selection(VirtualSnapshotPoint, VirtualSnapshotPoint, VirtualSnapshotPoint, PositionAffinity)	Instantiates a new Selection.
Selection(VirtualSnapshotPoint, VirtualSnapshotPoint)	Instantiates a new Selection with the given anchor and active points, and the insertion point is located at the active point.
Selection(VirtualSnapshotSpan, Boolean)	Instantiates a new Selection with the given extent. Anchor and active points are defined by isReversed, and the insertion point is located at the active point.

Fields

Invalid

A static instance of a selection that is invalid and can be used to check for instantiation.

Properties

ActivePoint	Gets the location of the movable selection endpoint, meaning if a user were to hold shift and click, this point would be changed to the location of the click. If this is an empty selection, this will be at the InsertionPoint.
AnchorPoint	Gets the location of the fixed selection endpoint, meaning if a user were to hold shift and click, this point would remain where it is. If this is an empty selection, this will be at the InsertionPoint.
End	Returns the larger of ActivePoint and AnchorPoint.
Extent	Returns the span from Start to End.
InsertionPoint	Gets the location where a caret should be rendered and edits performed.
InsertionPointAffinity	Gets the affinity of the insertion point. This is used in places like word-wrap where one buffer position can represent both the end of one line and the beginning of the next.
IsEmpty	True if AnchorPoint equals ActivePoint. False otherwise.
IsReversed	True if AnchorPoint is later in the document than ActivePoint. False otherwise.
IsValid	Gets whether this selection contains meaningful data.
Start	Returns the smaller of ActivePoint and AnchorPoint.
