public class Deflater
extends Deflater

This class provides support for general purpose compression using the popular ZLIB compression library. The ZLIB compression library was initially developed as part of the PNG graphics standard and is not protected by patents. It is fully described in the specifications at the java.util.zip package description.

Constructor Detail

Deflater

public Deflater(int level,
                boolean nowrap)
Creates a new compressor using the specified compression level. If 'nowrap' is true then the ZLIB header and checksum fields will not be used in order to support the compression format used in both GZIP and PKZIP.
Parameters:
level - the compression level (0-9)
nowrap - if true then use GZIP compatible compression

Deflater

public Deflater(int level)
Creates a new compressor using the specified compression level. Compressed data will be generated in ZLIB format.
Parameters:
level - the compression level (0-9)

Deflater

public Deflater()
Creates a new compressor with the default compression level. Compressed data will be generated in ZLIB format.
