Methods

  Name Description
Public method Contains(Object) Determines whether the collection contains the specified snapshot span.
Public method Contains(SnapshotSpan) Determines whether the collection contains the specified snapshot span.
Public method CopyTo(Array, Int32) Copies the snapshot spans in this collection to the specified array, starting at the specified index.
Public method CopyTo(array<SnapshotSpan[], Int32) Copies the collection to the specified array of snapshot spans at the specified location.
Public methodStatic member Difference Calculates the difference between two normalized snapshot span collections and normalizes the result.
Public method Equals Determines whether two snapshot span collections are the same. (Overrides Object.Equals(Object).)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)

Public method IndexOf(SnapshotSpan) Gets the index of the specified SnapshotSpan.
Public methodStatic member Intersection Calculates the intersection of two normalized snapshot span collections and normalizes the result.
Public method IntersectsWith Determines whether this collection intersects with another normalized snapshot span collection.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodStatic member Overlap Calculates the overlap of two normalized snapshot span collections and normalizes the result.
Public method OverlapsWith Determines whether this normalized snapshot span collection overlaps with another collection.
Public method ToString Converts the spans to a string. (Overrides Object.ToString().)
Public methodStatic member Union Calculates the union of two snapshot span collections and normalizes the result.

Operators

  Name Description
Public operatorStatic member Equality Determines whether two NormalizedSnapshotSpanCollection objects are the same.
Public operatorStatic member Implicit(NormalizedSnapshotSpanCollection to NormalizedSpanCollection) Converts the specified NormalizedSnapshotSpanCollection to a NormalizedSpanCollection.

Remarks

For more information about snapshots, see the section "A Closer Look at the Text Model and the Text View" in Inside the Editor.

The snapshot spans are sorted by start position. Adjacent and overlapping spans are combined.
