A mutable pair of (StartIndex, Length) that implements IIndexRange.

Properties
int	StartIndex `[get, set]`

int	Length `[get, set]`

int	EndIndex `[get, set]`

Properties inherited from Loyc.Syntax.IIndexRange
int	StartIndex `[get]`

int	EndIndex `[get]`

int	Length `[get]`

IndexRange	Normalize ()
	Ensures that StartIndex <= EndIndex by swapping the two if the Length is negative. More...

IndexRange	GetRangeOfOverlap (IndexRange other)
	Assuming both ranges are normalized, returns the range of overlap between them. If the ranges do not overlap, the Length of the returned range will be zero or negative. More...

bool	Overlaps (IndexRange other)
	Returns true if, assuming both ranges are normalized, the two regions share at least one common character. More...

bool	Contains (IndexRange other)
	Returns true if, assuming both ranges are normalized, the `other` range is entirely within the boundaries of this range. More...

bool Loyc.Syntax.IndexRange.Contains ( IndexRange other )

Returns true if, assuming both ranges are normalized, the other range is entirely within the boundaries of this range.

IndexRange Loyc.Syntax.IndexRange.GetRangeOfOverlap ( IndexRange other )

Assuming both ranges are normalized, returns the range of overlap between them. If the ranges do not overlap, the Length of the returned range will be zero or negative.

IndexRange Loyc.Syntax.IndexRange.Normalize ( )

inline

Ensures that StartIndex <= EndIndex by swapping the two if the Length is negative.

Exceptions

OverflowException An integer overflow occurred.

Returns: this.

bool Loyc.Syntax.IndexRange.Overlaps ( IndexRange other )

Returns true if, assuming both ranges are normalized, the two regions share at least one common character.

Note: this returns false if either of the ranges has a Length of zero and is at the boundary of the other range.
