Parameters

Return Value

Type: Microsoft.VisualStudio.Text.NormalizedSnapshotSpanCollection
A collection of zero or more snapshot spans in the top buffer to which the span maps.

Exceptions

Exception Condition
ArgumentNullException

span.Snapshot or match is nulla null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

trackingMode is not a valid SpanTrackingMode.

Remarks

match is called on each text buffer in the graph until it returns true. After that the predicate is not called again.
