Examples of BitOutputStream

ivory.core.compression.BitOutputStream
This class provides methods to write compressed integers to an outputstream.
The numbers are written into a byte starting from the most significant bit (i.e, left to right). There is an internal int buffer used before writting the bytes to the underlying stream, and the bytes are written into 32-bits integers. @author Roi Blanco
lupos.compression.bitstream.BitOutputStream
This class converts a bit output stream into a byte-oriented output stream.
