Method Detail

beforePacks

void beforePacks(AutomatedInstallData idata,
               java.lang.Integer npacks,
               AbstractUIProgressHandler handler)
                 throws java.lang.Exception

This method will be called from the unpacker before the installation of all packs will be performed.

Parameters:

idata - object containing the current installation data

npacks - number of packs which are defined for this installation

handler - a handler to the current used UIProgressHandler

Throws:

java.lang.Exception

beforePack

void beforePack(Pack pack,
              java.lang.Integer i,
              AbstractUIProgressHandler handler)
                throws java.lang.Exception

This method will be called from the unpacker before the installation of one pack will be performed.

Parameters:

pack - current pack object

i - current pack number

handler - a handler to the current used UIProgressHandler

Throws:

java.lang.Exception

isFileListener

boolean isFileListener()

Returns true if this listener would be informed at every file and directory installation, else false. If it is true, the listener will be called two times (before and after) for every action. Handle carefully, else performance problems are possible.

Returns:

true if this listener would be informed at every file and directory installation, else false

beforeDir

void beforeDir(java.io.File dir,
             PackFile pf)
               throws java.lang.Exception

This method will be called from the unpacker before one directory should be created. If parent directories should be created also, this method will be called for every directory beginning with the base.

Parameters:

dir - current File object of the just directory which should be created

pf - corresponding PackFile object

Throws:

java.lang.Exception

afterDir

void afterDir(java.io.File dir,
            PackFile pf)
              throws java.lang.Exception

This method will be called from the unpacker after one directory was created. If parent directories should be created, this method will be called for every directory beginning with the base.

Parameters:

dir - current File object of the just created directory

pf - corresponding PackFile object

Throws:

java.lang.Exception

beforeFile

This method will be called from the unpacker before one file should be installed.

Parameters:

file - current File object of the file which should be installed

pf - corresponding PackFile object

Throws:
