Description

Mutable boxed and unboxed arrays in the IO monad.

Synopsis

type IOArray = IOSpecific3 BoxedMutableArray type IOUArray = IOSpecific3 UnboxedMutableArray castIOUArray :: forall i e e'. (Ix i, Enum i, Unboxed e, Unboxed e') => IOUArray i e -> IOUArray i e' module Data.ArrayBZ.MArray hGetArray :: Handle -> IOUArray Int Word8 -> Int -> IO Int hPutArray :: Handle -> IOUArray Int Word8 -> Int -> IO ()

IO arrays with boxed elements

type IOArray = IOSpecific3 BoxedMutableArray

Boxed mutable arrays in IO monad

IO arrays with unboxed elements

type IOUArray = IOSpecific3 UnboxedMutableArray

Unboxed mutable arrays in IO monad

castIOUArray :: forall i e e'. (Ix i, Enum i, Unboxed e, Unboxed e') => IOUArray i e -> IOUArray i e'

Casts an IOUArray with one element type into IOUArray with a different element type (upper bound is recalculated).

Overloaded mutable array interface

module Data.ArrayBZ.MArray

Doing I/O with IOUArrays

hGetArray

:: Handle Handle to read from -> IOUArray Int Word8 Array in which to place the values -> Int Number of Word8s to read -> IO Int Returns: the number of Word8s actually read, which might be smaller than the number requested if the end of file was reached. Reads a number of Word8s from the specified Handle directly into an array.

hPutArray

:: Handle Handle to write to -> IOUArray Int Word8 Array to write from -> Int Number of Word8s to write -> IO () Writes an array of Word8 to the specified Handle.
