pack-priv final Class Bzip2BitWriter

extends Object
Class Inheritance
Imports
io.netty.buffer.ByteBuf
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 the ByteBuf when sufficient bits have been accumulated.

Field Summary

Modifier and TypeField and Description
private long
bitBuffer

A buffer of bits waiting to be written to the output stream.

private int
bitCount

The number of bits currently buffered in bitBuffer.

Writes up to 32 bits to the output ByteBuf.

pack-priv void
writeBoolean(ByteBuf out, final boolean
The bit to write
value)

Writes a single bit to the output ByteBuf.

pack-priv void
writeInt(ByteBuf out, final int
The integer to write
value)

Writes an integer as 32 bits to the output ByteBuf.

pack-priv void
writeUnary(ByteBuf out, int
The number of 1 to write
value)

Writes a zero-terminated unary number to the output ByteBuf.
