Parsing iteratees

iterHeaders :: (Functor m, Monad m) => [IdentifyCodec] -> Iteratee ByteString m CacheFile

Parse only the global and track headers of a zoom-cache file, returning a CacheFile

Enumeratee

enumCacheFile :: (Functor m, MonadIO m) => [IdentifyCodec] -> Enumeratee ByteString Stream m a

An enumeratee of a zoom-cache file, from the global header onwards. The global and track headers will be transparently read, and the CacheFile visible in the Stream elements.

enumStream :: (Functor m, MonadIO m) => CacheFile -> Enumeratee ByteString Stream m a

An enumeratee of zoom-cache data, after global and track headers have been read, or if the CacheFile has been acquired elsewhere.

Iteratee maps

mapStream :: (Functor m, MonadIO m) => [IdentifyCodec] -> (Stream -> m ()) -> Iteratee ByteString m ()

Map a monadic Stream processing function over an entire zoom-cache file.

mapPackets :: (Functor m, MonadIO m) => [IdentifyCodec] -> (Packet -> m ()) -> Iteratee ByteString m ()

Map a monadic Packet processing function over an entire zoom-cache file.

mapSummaries :: (Functor m, MonadIO m) => [IdentifyCodec] -> (ZoomSummary -> m ()) -> Iteratee ByteString m ()

Map a monadic Summary processing function over an entire zoom-cache file.
