Data.Array.Unboxed

Contents

Description

Unboxed immutable arrays.

Synopsis

dataUArray i e
moduleData.Array.IArray

Arrays with unboxed elements

dataUArray i eSource #

Arrays with unboxed elements. Instances ofIArray are provided forUArray with certain element types (Int,Float,Char, etc.; see theUArray class for a full list).

AUArray will generally be more efficient (in terms of both time and space) than the equivalentArray with the same element type. However,UArray is strict in its elements - so don't useUArray if you require the non-strictness thatArray provides.

Because theIArray interface provides operations overloaded on the type of the array, it should be possible to just change the array type being used by a program from sayArray toUArray to get the benefits of unboxed arrays (don't forget to importData.Array.Unboxed instead ofData.Array).
