void compactArchive(ccs.cdb.CDBeeTree bt,
                    boolean isChg)
              throws ccs.ArghException,
                     ccs.LoseException,
                     java.io.IOException

Comapct an archive, with optional password change (not CDBs).

Parameters:

bt - The BeeTree to compact. If isChg, caller must ensure that it isn't a CDB.

isChg - Whether to change the password (not CDBs).

Throws:

ccs.ArghException

ccs.LoseException

java.io.IOException

determineDefaultDirectory

java.io.File determineDefaultDirectory(BrowserLogic bl)
                                 throws java.lang.IllegalStateException

Returns the default folder to start in when looking for the location of an archive; this is the current folder of the device in the specified browser panel, which is required to be a disk vdevice.

Throws:

java.lang.IllegalStateException - if not in a disk device.

getArchFile

void getArchFile(ArchLoadData ald,
                 BrowserLogic bl)
           throws java.lang.IllegalStateException,
                  java.lang.InterruptedException

Return the location of the new or current archive.

Parameters:

ald - The ArchLoadData (or ArchCreateData) to return the result in.

bl - The browser containing the folder to start from.

Throws:

java.lang.IllegalStateException - if not in a disk device.

java.lang.InterruptedException - If user cancels.

getArchPassword

void getArchPassword(ArchLoadData ald)
               throws java.lang.InterruptedException

Obtain the user's attempt at a password. Used for both create, and all arch-open routes where required.

Throws:

java.lang.InterruptedException - If user cancels.

mangleArchPassword

void mangleArchPassword(byte[] pwd)

Lightly mangle the supplied password. It was formerly thought important for various (marketing?) reasons that it shouldn't be easy to register an Archive with Checkpoint without going through the proper registration process. The reasons for this desideratum are now lost in the mists; the legacy remains as a backward-compatibilty wartlet.

openZip

void openZip(java.io.File zipf,
             BrowserLogic bl,
             boolean isTransient)
       throws java.io.IOException

Open a zip.

Throws:
