final class Bzip2BitWriter extends java.lang.Object
A bit writer that allows the writing of single bit booleans, unary numbers, bit strings of arbitrary length (up to 32 bits), and bit aligned 32-bit integers. A single byte at a time is written to theByteBuf
when sufficient bits have been accumulated.
