Examples of CBZip2OutputStream

at.molindo.thirdparty.org.apache.tools.bzip2.CBZip2OutputStream

An output stream that compresses into the BZip2 format (without the file header chars) into another stream.

The compression requires large amounts of memory. Thus you should call the {@link #close() close()} method as soon as possible, to forceCBZip2OutputStream to release the allocated memory.

You can shrink the amount of allocated memory and maybe raise the compression speed by choosing a lower blocksize, which in turn may cause a lower compression ratio. You can avoid unnecessary memory allocation by avoiding using a blocksize which is bigger than the size of the input.

You can compute the memory usage for compressing by the following formula:

 <code>400k + (9 * blocksize)</code>.

To get the memory required for decompression by {@link CBZip2InputStream CBZip2InputStream} use

 <code>65k + (5 * blocksize)</code>.

Memory usage by blocksize
Blocksize	Compression memory usage	Decompression memory usage
100k	1300k	565k
200k	2200k	1065k
300k	3100k	1565k
400k	4000k	2065k
500k	4900k	2565k
600k	5800k	3065k
700k	6700k	3565k
800k	7600k	4065k
900k	8500k	4565k

For decompression CBZip2InputStream allocates less memory if the bzipped input is smaller than one block.
