Utilities

unsafeWithByteString :: ByteString -> (Buffer -> Offset -> IO a) -> IO a

Using ByteString as Buffer and call the IO action of the second argument by passing the start point and the offset of the ByteString. Note that if a ByteString is created newly, its offset is 0.

copy :: Buffer -> ByteString -> IO Buffer

Copying the bytestring to the buffer. This function returns the point where the next copy should start.

bufferIO :: Buffer -> Int -> (ByteString -> IO a) -> IO a

Class to read a buffer

class Readable a where

Methods

read8 :: a -> IO Word8

Reading one byte as Word8 and ff one byte.

readInt8 :: a -> IO Int

Reading one byte as Int and ff one byte. If buffer overrun occurs, -1 is returned.

ff :: a -> Offset -> IO ()

Fast forward the offset pointer. The boundary is not checked.

remainingSize :: a -> IO Int

Returning the length of the remaining

withCurrentOffSet :: a -> (Buffer -> IO b) -> IO b

Executing an action on the current offset pointer.

save :: a -> IO ()

Memorizing the current offset pointer.

savingSize :: a -> IO Int

Getting how many bytes from the saved offset pinter.

Reading from buffer

data ReadBuffer

Read only buffer. To ensure that the internal is not modified, this is an abstract data type.

Instances

Readable ReadBuffer

Defined in Network.ByteOrder

Methods

read8 :: ReadBuffer -> IO Word8

readInt8 :: ReadBuffer -> IO Int

ff :: ReadBuffer -> Offset -> IO ()

remainingSize :: ReadBuffer -> IO Int

withCurrentOffSet :: ReadBuffer -> (Buffer -> IO b) -> IO b

save :: ReadBuffer -> IO ()

savingSize :: ReadBuffer -> IO Int

withReadBuffer :: ByteString -> (ReadBuffer -> IO a) -> IO a

Converting ByteString to ReadBuffer and run the action with it.

read16 :: Readable a => a -> IO Word16

Reading two bytes as Word16 and ff two bytes.

read24 :: Readable a => a -> IO Word32

Reading three bytes as Word32 and ff three bytes.

read32 :: Readable a => a -> IO Word32

Reading four bytes as Word32 and ff four bytes.

extractByteString :: Readable a => a -> Int -> IO ByteString

Extracting ByteString from the current offset. The contents is copied, not shared. Its length is specified by the 2nd argument. If the length is positive, the area after the current pointer is extracted and FF the length finally. If the length is negative, the area before the current pointer is extracted and does not FF.

Writing to buffer

data WriteBuffer

Read and write buffer.

write8 :: WriteBuffer -> Word8 -> IO ()

Write one byte and ff one byte. If buffer overrun occurs, BufferOverrun is thrown.

write16 :: WriteBuffer -> Word16 -> IO ()

Write two bytes and ff one byte. If buffer overrun occurs, BufferOverrun is thrown.

write24 :: WriteBuffer -> Word32 -> IO ()

Write three bytes and ff one byte. If buffer overrun occurs, BufferOverrun is thrown.

write32 :: WriteBuffer -> Word32 -> IO ()

copyByteString :: WriteBuffer -> ByteString -> IO ()

Copy the content of ByteString and ff its length. If buffer overrun occurs, BufferOverrun is thrown.

shiftLastN :: WriteBuffer -> Offset -> Int -> IO ()

Shifting the N-bytes area just before the current pointer. Offset is the distance from the offset pointer. If Offset is positive, shift it to right. If Offset is negative, shift it to left.

toByteString :: WriteBuffer -> IO ByteString

Copy the area from start to the current pointer to ByteString.

currentOffset :: WriteBuffer -> IO Buffer

Getting the offset pointer.

data ByteString

A space-efficient representation of a Word8 vector, supporting many efficient operations.

A ByteString contains 8-bit bytes, or by using the operations from Data.ByteString.Char8 it can be interpreted as containing 8-bit characters.
