IMappingPoint.GetPoint Method (ITextSnapshot, PositionAffinity)

Maps the point to a particular ITextSnapshot.

Namespace:  Microsoft.VisualStudio.Text
Assembly:  Microsoft.VisualStudio.Text.Data (in Microsoft.VisualStudio.Text.Data.dll)


Function GetPoint ( _
    targetSnapshot As ITextSnapshot, _
    affinity As PositionAffinity _
) As Nullable(Of SnapshotPoint)
Nullable<SnapshotPoint> GetPoint(
    ITextSnapshot targetSnapshot,
    PositionAffinity affinity
Nullable<SnapshotPoint> GetPoint(
    ITextSnapshot^ targetSnapshot, 
    PositionAffinity affinity
abstract GetPoint : 
        targetSnapshot:ITextSnapshot * 
        affinity:PositionAffinity -> Nullable<SnapshotPoint> 
function GetPoint(
    targetSnapshot : ITextSnapshot, 
    affinity : PositionAffinity
) : Nullable<SnapshotPoint>


  • affinity
    Type: Microsoft.VisualStudio.Text.PositionAffinity
    If the mapping is ambiguous (the position lies on a source span seam), this parameter affects the mapping as follows:
    if affinity is Predecessor, the mapping targets the position immediately after the preceding character in the anchor buffer
    if affinity is Successor, the mapping targets the position immediately before the following character in the anchor buffer
    This parameter has no effect if the mapping is unambiguous.

Return Value

Type: System.Nullable<SnapshotPoint>
A nullable SnapshotPoint.


Exception Condition

targetSnapshot is null.


In general, a source span seam occurs at the end of a source span of nonzero length and the beginning of a source span of nonzero length, and coincides with zero or more source spans of zero length. Every span on a seam has a point in the result collection.
