The TextSpanHelper type exposes the following members.

Methods

	Name	Description
	Clear	Sets the members of the specified span to an empty state.
	ContainsExclusive	Determines whether the given position is contained in the given span, not including the start and end points.
	ContainsInclusive	Determines whether the given position is in the span, including the start and end points.
	EndsAfterEndOf	Determines whether the first span ends after the end of the second span.
	EndsAfterStartOf	Determines whether the first span ends after the start of the second span.
	EndsBeforeEndOf	Determines whether the first span ends before the end of the second span.
	EndsBeforeStartOf	Determines whether the first span ends before the start of the second span.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Intersects	Determines whether the first span intersects the second span.
	IsAfterEndOf	Determines whether the given position occurs after the end of the given span.
	IsBeforeStartOf	Determines whether the given position occurs before the start of the given span.
	IsEmbedded	Determines whether the first span is wholly contained in the second span.
	IsEmpty	Determines whether the given span is empty.
	IsPositive	Determines whether the start of the given span occurs before the end of the span.
	IsSameSpan	Determines whether two spans are the same.
	MakePositive	Makes the given span positive.
	Merge	Merges the two given spans to create a new span.
	Normalize	Pins the ends of the given span to the actual line lengths in the given text buffer.
	StartsAfterEndOf	Determines whether the first span starts after the end of the second span.
	StartsAfterStartOf	Determines whether the first span starts after the start of the second span.
	StartsBeforeEndOf	Determines whether the first span starts before the end of the second span.
	StartsBeforeStartOf	Determines whether the first span starts before the start of the second span.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	ValidCoord	Determines whether the given position is valid for the given source buffer.
	ValidSpan	Determines whether the given span lies within the given source buffer.

Remarks

Manipulation includes clearing, normalizing, merging, and converting to and from a TextSpan2 class. Comparisons include determining the relationship of a point to a span and the relationship of two spans. Validation is done for a position or a span in a source buffer.

Notes to Implementers

All methods in this class are static and there is nothing from which to inherit.

Notes to Callers

All methods in this class are static and can be called at any time.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
