Maps the point to an insertion point in a matching ITextBuffer.

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

Function GetInsertionPoint ( _
match As Predicate(Of ITextBuffer) _
) As Nullable(Of SnapshotPoint)
Nullable<SnapshotPoint> GetInsertionPoint(
Predicate<ITextBuffer> match

Nullable<SnapshotPoint> GetInsertionPoint(

abstract GetInsertionPoint :
match:Predicate<ITextBuffer> -> Nullable<SnapshotPoint>
function GetInsertionPoint(
match : Predicate<ITextBuffer>
) : Nullable<SnapshotPoint>
Parameters
- match
Type: System.Predicate<ITextBuffer>
The predicate used to match the ITextBuffer.
Return Value
Type: System.Nullable<SnapshotPoint>
A SnapshotPoint in the matching buffer, or nulla null reference (Nothing in Visual Basic) if the point does not appear in that buffer.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | match is nulla null reference (Nothing in Visual Basic). |
Remarks
In the usual case, this computation maps through projection buffers, subject to caller approval using match. If there is ambiguity in a projection mapping, it is resolved by calling GetTypicalInsertionPosition.
match is called for each text buffer in the buffer graph until a match is found. This selects the buffer of interest, and the predicate will not be called again. If no match is found, the result is nulla null reference (Nothing in Visual Basic).
