Declaration
public virtual object Clone()
Returns
Type Description
System.Object

Contains(Position)

true if the position is inside the range

Declaration
public virtual bool Contains(Position position)
Parameters
Type Name Description
Position position
Returns
Type Description
System.Boolean

GetIntersection(ContentRange)

Returns the normalized range that represents the intersection between this range and the other, or null if they don't overlap.

Declaration
public virtual ContentRange GetIntersection(ContentRange other)
Parameters
Type Name Description
ContentRange other
Returns
Type Description
ContentRange

Normalize()

swaps from and upto if the range is reversed

Declaration
public virtual void Normalize()

Overlaps(ContentRange)

true if there is an overlap between this and the other range

Declaration
public virtual bool Overlaps(ContentRange other)
Parameters
Type Name Description
ContentRange other
Returns
Type Description
System.Boolean

ReduceRanges(List<ContentRange>, ContentRange.ReductionAllowedTest)

Helper function to reduce a set of same-parent ranges to the smallest set of same-parent ranges necessary to span the content from the first to the last range.

Declaration
public static List<ContentRange> ReduceRanges(List<ContentRange> rangesToReduce, ContentRange.ReductionAllowedTest additionalCondition)
Parameters
Type Name Description
System.Collections.Generic.List<ContentRange> rangesToReduce

Set of same-parent ranges to be processed
ContentRange.ReductionAllowedTest additionalCondition

Additional condition that will be evaluated to determine if the range can be reduced. Can be null, in which case ranges will always be reduced if possible.
Returns
Type Description
System.Collections.Generic.List<ContentRange>

The smallest set of same-parent ranges necessary to span all content in the input ranges (and anything between them)
Remarks

This method is used as a helper in the implementation of IFrameworkDocument.GetMarkupDataRanges in the EditorApi.

The input range should be sorted so that all ranges appear in the correct order. The output ranges will also be sorted in this order.

NOTE: The input ranges may get modified in the process.

Reverse()

swaps from and upto

Declaration
public virtual void Reverse()

SetFromSelection(IContentSelection)

Clone the from and upto locations from the selection.

Declaration
public virtual void SetFromSelection(IContentSelection selection)
Parameters
Type Name Description
IContentSelection selection

Implements

System.ICloneable
