pack-priv Class Bzip2BitReader

extends Object
Class Inheritance
Imports
io.netty.buffer.ByteBuf
An bit reader that allows the reading of single bit booleans, bit strings of arbitrary length (up to 32 bits), and bit aligned 32-bit integers. A single byte at a time is read from the ByteBuf when more bits are required.

Field Summary

Modifier and TypeField and Description
private long
bitBuffer

private int
bitCount

The number of bits currently buffered in bitBuffer.

private ByteBuf
in

The ByteBuf from which to read data.

private static final int
MAX_COUNT_OF_READABLE_BYTES

Maximum count of possible readable bytes to check.
