Public Structure SnapshotSpan

public struct SnapshotSpan

public value class SnapshotSpan

[<Sealed>]
type SnapshotSpan =  struct end

JScript supports the use of structures, but not the declaration of new ones.

The SnapshotSpan type exposes the following members.

Constructors

	Name	Description
	SnapshotSpan(ITextSnapshot, Span)	Initializes a new instance of a SnapshotSpan with the specified snapshot and span.
	SnapshotSpan(SnapshotPoint, SnapshotPoint)	Initializes a new instance of a SnapshotSpan from two SnapshotPoint objects.
	SnapshotSpan(SnapshotPoint, Int32)	Initializes a new instance of a SnapshotSpan from an existing SnapshotPoint and a specified length.
	SnapshotSpan(ITextSnapshot, Int32, Int32)	Initializes a new instance of a SnapshotSpan with the specified snapshot, start point, and length.

	Intersection(Span)	Calculates the intersection with the given span.
	IntersectsWith(SnapshotSpan)	Determines whether the specified snapshot span intersects this span.
	IntersectsWith(Span)	Determines whether the specified span intersects this span.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Overlap(SnapshotSpan)	Gets the overlap with the given SnapshotSpan.
	Overlap(Span)	Getss the overlap with the given span.
	OverlapsWith(SnapshotSpan)	Determines whether another span overlaps this span.
	OverlapsWith(Span)	Determines whether simpleSpan overlaps this span.
	ToString	Converts this snapshot span to a string. (Overrides ValueType.ToString().)
	TranslateTo	Translates this snapshot span to a different snapshot of the same ITextBuffer.
