BitStream

About

Bit stream codec implementation in ActionScript3 (BitStream.as is the codec). Faciliates creation of a binary string that consist of arbitrary-bit-length items. (De)Serializes into ByteArray.

  • Can be used in variety of home-made binary codecs.
  • Can be used with Base64 codec to send the encoded binary string over JSON, HTTP or other non-binary transport.

Features:

  • writeBits 1...32 bits in length.
  • readBits 1...32 bits in length.
  • saveByteArray - aligns to 32bit word. Pads with zeroes.
  • loadByteArray

TODO

  • writeSignedBits(-30, 6) - one bit (leftmost) for the sign(negative=1, positive=0), then encodes the number in N-1 bits
