protected java.util.Hashtable addedDirs

doubleFilePass

protected boolean doubleFilePass

skipWriting

protected boolean skipWriting

duplicate

Deprecated. Use Archiver.setDuplicateBehavior(String) instead.

protected boolean addingNewFiles

true when we are adding new files into the Zip file, as opposed to adding back the unchanged files

Constructor Detail

AbstractZipArchiver

public AbstractZipArchiver()

Method Detail

getComment

public java.lang.String getComment()

setComment

public void setComment(java.lang.String comment)

getEncoding

public java.lang.String getEncoding()

setEncoding

public void setEncoding(java.lang.String encoding)

setCompress

public void setCompress(boolean compress)

isCompress

public boolean isCompress()

setUpdateMode

public void setUpdateMode(boolean update)

isInUpdateMode

public boolean isInUpdateMode()

setFilesonly

public void setFilesonly(boolean f)

If true, emulate Sun's jar utility by not adding parent directories; optional, defaults to false.

isFilesonly

public boolean isFilesonly()

setRoundUp

public void setRoundUp(boolean r)

Whether the file modification times will be rounded up to the next even number of seconds.

Zip archives store file modification times with a granularity of two seconds, so the times will either be rounded up or down. If you round down, the archive will always seem out-of-date when you rerun the task, so the default is to round up. Rounding up may lead to a different type of problems like JSPs inside a web archive that seem to be slightly more recent than precompiled pages, rendering precompilation useless.

isRoundUp

public boolean isRoundUp()

zipFile

protected void zipFile(java.io.InputStream in,
                       ZipOutputStream zOut,

in - the stream to read data for the entry from.

zOut - the stream to write to.

vPath - the name this entry shall have in the archive.

                throws java.io.IOException,
                       ArchiverException

Method that gets called when adding from java.io.File instances.

This implementation delegates to the six-arg version.

Parameters:

entry - the file to add to the archive

zOut - the stream to write to

vPath - the name this entry shall have in the archive

Throws:

java.io.IOException

ArchiverException

zipDir

protected void zipDir(org.codehaus.plexus.components.io.resources.PlexusIoResource dir,
                      ZipOutputStream zOut,

Create an empty zip file

Returns:

true for historic reasons

Throws:

ArchiverException

cleanUp

protected void cleanUp()

Do any clean up necessary to allow this instance to be used again.

When we get here, the Zip file has been closed and all we need to do is to reset some globals.

This method will only reset globals that have been changed during execute(), it will not alter the attributes or nested child elements. If you want to reset the instance so that you can later zip a completely different set of files, you must use the reset method.

Overrides:

cleanUp in class AbstractArchiver

See Also:

reset()

reset

public void reset()

Makes this instance reset all attributes to their default values and forget all children.
