Data.Iteratee.IO.Handle
Contents
Description
Random and Binary IO with generic Iteratees. These functions use Handles for IO operations, and are provided for compatibility. When available, the File Descriptor based functions are preferred as these wastefully allocate memory rather than running in constant space.
- enumHandle :: forall s el m a. (ReadableChunk s el, MonadIO m) => Handle -> EnumeratorGM s el m a
- enumHandleRandom :: forall s el m a. (ReadableChunk s el, MonadIO m) => Handle -> EnumeratorGM s el m a
- fileDriverHandle :: (MonadIO m, ReadableChunk s el) => IterateeG s el m a -> FilePath -> m a
- fileDriverRandomHandle :: (MonadIO m, ReadableChunk s el) => IterateeG s el m a -> FilePath -> m a
File enumerators
enumHandle :: forall s el m a. (ReadableChunk s el, MonadIO m) => Handle -> EnumeratorGM s el m aSource
The enumerator of a file Handle. This version enumerates over the entire contents of a file, in order, unless stopped by the iteratee. In particular, seeking is not supported.
enumHandleRandom :: forall s el m a. (ReadableChunk s el, MonadIO m) => Handle -> EnumeratorGM s el m aSource
The enumerator of a Handle: a variation of enumHandle that supports RandomIO (seek requests)
Iteratee drivers
fileDriverHandle :: (MonadIO m, ReadableChunk s el) => IterateeG s el m a -> FilePath -> m aSource
Process a file using the given IterateeGM. This function wraps enumHandle as a convenience.
fileDriverRandomHandle :: (MonadIO m, ReadableChunk s el) => IterateeG s el m a -> FilePath -> m aSource
Process a file using the given IterateeGM. This function wraps enumHandleRandom as a convenience.
