zipPathNameSaveToPathName

public static void zipPathNameSaveToPathName(java.lang.String fileOrFolderPathName,
                                             java.lang.String saveToThisFilePathName)
                                      throws java.io.IOException

Throws:

java.io.IOException

zipFileOrFolder

public static byte[] zipFileOrFolder(java.io.File fileOrFolder)
                              throws java.io.IOException

Throws:

java.io.IOException

zipFileOrFolder

public static byte[] zipFileOrFolder(java.io.File fileOrFolder,
                                     int compressionLevel0None9Most,
                                     java.lang.String commentOfZipFile)
                              throws java.io.IOException

Zips 1 file or if its a folder, zips everything in that folder recursively. Returns the bytes of a zip or jar file. For any x.jar, you can rename x.jar to x.zip and it works as a zip file. TEMPORARILY NO COMPRESSION LEVEL CHANGE OR COMMENTS. TEST THIS FIRST.

Throws:

java.io.IOException

zipCsArray

public static byte[] zipCsArray(CS[] namesAndByteArrays)

for all CS in namesAndByteArrays[]: use CS.name() and (byte[]) CS.L(byte[].class)

getFileNames

public static java.lang.String[] getFileNames(byte[] zipBytes)

TODO: for efficiency, dont read the bytes, get only the names

unzip

public static Jars.ZipEntryAndByteArray[] unzip(java.util.zip.ZipInputStream zipIn)

unzip all files in zipIn

get1FileFromZip

public static byte[] get1FileFromZip(java.lang.String filePathNameInZip,
                                     byte[] zipBytes)
