Method Detail

zip

public static void zip(String[] directoriesAndFiles,
                       File dest,
                       CRC32 crc)
                throws IOException

Create a zip file on the given directoriesAndFiles argument and store the create content in a file denoted by the path in the given dest argument

Parameters:

directoriesAndFiles - the directories and files to zip (recursively)

dest - the zip destination file that will contains the zipped version of the first argument.

crc - the CRC32 of all zipentries. Can be null if no crc is needed.

Throws:

IOException - if the zip file cannot be created.

zipDirectoriesAndFiles

public static byte[] zipDirectoriesAndFiles(String[] directoriesAndFiles,
                                            CRC32 crc)
                                     throws IOException

Create a zip file that contains all the directory listed in directories parameter.

Parameters:

directoriesAndFiles - the list of directories and files to be zipped.

crc - the CRC32 of all zipentries. Can be null if no crc is needed.

Returns:

the zip file as a byte[].

Throws:

IOException - if the zip file cannot be created.

zipIt

protected static void zipIt(ZipOutputStream zos,
                            String[] directoriesAndFiles,
                            CRC32 crc)
                     throws IOException

Zip directory content in the given output stream

Parameters:

zos - the output stream in which to store the zipped directory

directoriesAndFiles - a list of directories and files to be zipped

Throws:

IOException - if a zip entry cannot be created.

zipDirectory

protected static void zipDirectory(String directoryName,
                                   int iBaseFolderLength,
                                   ZipOutputStream zos,

                            throws IOException

Add the given directory into the zipStream.

Parameters:

directoryName - the directory to be added in the zip.

iBaseFolderLength - the index in the directoryName from which starts the actual zip entry name.

zos - the stream to write into.

crc - the CRC32 of all zipentries. Can be null if no crc is needed.

Throws:

IOException - if the zip file cannot be written.

zipFile

protected static void zipFile(String filePath,
                              int iBaseFolderLength,
                              ZipOutputStream jos,

Parameters:

filePath - the file to be added in the zip.

iBaseFolderLength - the index in the directoryName from which starts the actual zip entry name.

jos - the stream to write into.

crc - the CRC32 of all zipentries. Can be null if no crc is needed.

Throws:

IOException - if the zip file cannot be written.

unzip
