SYNOPSIS

#include <zipoutputstreambuf.h>

Inherits zipios::DeflateOutputStreambuf.

Public Types

enum CompressionLevels { NO_COMPRESSION = Z_NO_COMPRESSION, BEST_SPEED = Z_BEST_SPEED, BEST_COMPRESSION = Z_BEST_COMPRESSION, DEFAULT_COMPRESSION = Z_DEFAULT_COMPRESSION }

ZipOutputStreambuf (streambuf *outbuf, bool del_outbuf=false)
ZipOutputStreambuf constructor. void closeEntry ()
Closes the current entry, and positions the stream read pointer at the beginning of the next entry (if there is one). void close ()
Calls finish. void finish ()
Closes the current entry (if one is open), then writes the Zip Central Directory Structure closing the ZipOutputStream. void putNextEntry (const ZipCDirEntry &entry)
Begins writing the next entry. void setComment (const string &comment)
Sets the global comment for the Zip archive. void setLevel (int level)
Sets the compression level to be used for subsequent entries. void setMethod (StorageMethod method)
Sets the compression method to be used. virtual ~ZipOutputStreambuf ()
Destructor.

uint32 getCrc32 () const
Returns the CRC32 for the current stream. uint32 getCount () const
