Initializer

init(indexesIn:)

Initializes an allocated NSIndexSet object with an index range.

Declaration

init(indexesIn range: NSRange)

Parameters

indexRange

An index range. Must be in the range 0 .. NSNotFound - 1..

Return Value

Initialized NSIndexSet object with indexRange.

Discussion

This method raises an rangeException when indexRange would add an index that exceeds the maximum allowed value for unsigned integers.

The resulting index set has a firstIndex equal to the location of indexRange, and a count equal to the length of indexRange. Specifying a zero-length range results in an empty index set.

This method is a designated initializer for NSIndexSet.
