// Class Methods
public static File gz(File aSourceFile) throws ZipException;

Packs the given directory into a new zipfile with the given name
returns a new zipfile with the given name
public static File ungz(File aSourceFile) throws ZipException;

Packs the given directory into a new zipfile with the given name
returns a new zipfile with the given name
public static void createTARWithPathEntries(File aDirectory, File aTarFile,
boolean doGZIP) throws ZipException;

Packs the given directory into a new zipfile with the given name
public static void createTARWithPathEntries(Collection aFilesCollection,
File aDestinationFile, String aParentStartPath, boolean doGZIP)
throws ZipException;

Creates a zip file out of a collection of files. The zip file created will have the path information of each file so that when it is unzipped then it is copied into the specific directory format. The relative path name is also given as parameter. Also fecilitates with the feature of adding empty directory entries. (i.e if the list of files contains a directory then it is added as a directory zipentry.) *
public static void unTarWithPath(File aSourceTarFile, String aDestinationDir,
boolean doUnGZIP) throws ZipException;

Unzips a zip file to the given directory structure as how the zipentry specifies. If a directory zip entry exists then a empty directory with the entry name is created.
public static final boolean packAndDeleteDirContents(File aTarFile, File
aDir, String aExtension, long aOlderThanMillis, boolean doGZIP);

Deletes all the files in a directory excluding the subdirectories files, if the given file is a directory but does not delete the directory itself. Before it Zips the given Files to another place.
returns success
public static final boolean packDirContents(File aTarFile, File aDir, String
aExtension, long aOlderThanMillis, boolean doGZIP);

Deletes all the files in a directory excluding the subdirectories files, if the given file is a directory but does not delete the directory itself. Before it Zips the given Files to another place.
returns success
public static void createTar(Collection aFilesCollection, File
aDestinationFile, boolean doGZIP) throws ZipException;

Creates a zip file out of a collection of files.
public static void createTar(String aFileName, InputStream aInputStream,
File aDestinationFile, boolean doGZIP) throws ZipException;

Creates a zip file out of a InputStream.
public static void addToTar(Collection aFilesCollection, File aSourceTarFile,
File aDestinationTarFile) throws ZipException;

Add a file(s) to the zip file from a collection of files.
public static void addToTar(File aFileToAdd, File aSourceZipFile, File
aDestinationZipFile) throws ZipException;

Add a file(s) to the zip file from a collection of files.
public static List unTAR(File aSourceTarFile, String aDestinationDir,
boolean doUnGZIP) throws ZipException;

Unzips a zip file to the given directory and returns a map of unzipped-files
returns a list of unzipped-files
public static List unTar(File aSourceTarFile, String aDestinationDir,
boolean aReplacePercentInPath, boolean doUnGZIP) throws ZipException;

UnTars a Tar file to the given directory and returns a map of unTarped-files
returns a list of unTarped-files
public static List unTar(File aSourceTarFile, String aSubPath, String
aDestinationDir, boolean doUnGZIP) throws ZipException;

Unzips a zip file to the given directory and returns a map of unzipped-files. Will only unzip files with the given subPath.
returns a list of unzipped-files
public static List unTar(File aSourceTarFile, String aSubPath, String
aDestinationDir, boolean aReplacePercentInPath, boolean doUnGZIP)
throws ZipException;

Unzips a zip file to the given directory and returns a map of unzipped-files. Will only unzip files with the given subPath.
returns a list of unzipped-files
public static Collection getTAREntries(File aSourceTarFile, boolean doUnGZIP)
throws ZipException;

Extracts the entries of the given zip-file.
returns the entries of the given zip-file
public static char getFileSeparator(File aZipArchive);

Parses the Entries of the given Zip archive and looks for the file separator character, if it is a directory.

Both operating systems use different file separators when creating a zip archive. if it should be unzipped on the other OS, this might lead to errors.
returns file separator
