Private Attributes | |
int | block_size_100k_ |
compression block size (1-9; 9 default). 9 is best compression, most memory | |
int | bzerror_ |
last error from bzlib | |
BZFILE * | bzfile_ |
bzlib compressed file stream | |
int | verbosity_ |
level of debugging output (0-4; 0 default). 0 is silent, 4 is max verbose debugging output | |
int | work_factor_ |
compression behavior for worst case, highly repetitive data (0-250; 30 default) |
BZ2Stream uses libbzip2 (http://www.bzip.org) for reading/writing compressed data in the BZ2 format.
