doubleFilePass

protected boolean doubleFilePass

If this flag is true, execute() will run most operations twice, the first time with skipWriting set to true and the second time with setting it to false.

The only situation in Ant's current code base where this is ever going to be true is if the jar task has been configured with a filesetmanifest other than "skip".

skipWriting

protected boolean skipWriting

whether the methods should just perform some sort of dry-run.

Will only ever be true in the first pass if the task performs two passes because doubleFilePass is true.

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 If you round down, the archive will always seem out-of-date when you rerun the task, so the default is to round up.

                                      throws BuildException

Collect the resources that are newer than the corresponding entries (or missing) in the original archive.

If we are going to recreate the archive instead of updating it, all resources should be considered as new, if a single one is. Because of this, subclasses overriding this method must call super.getResourcesToAdd and indicate with the third arg if they already know that the archive is out-of-date.

This method first delegates to getNonFileSetResourceToAdd and then invokes the FileSet-arg version. All this to keep backwards compatibility for subclasses that don't know how to deal with non-FileSet ResourceCollections.

Parameters:

rcs - The resource collections to grab resources from

zipFile - intended archive file (may or may not exist)

needsUpdate - whether we already know that the archive is out-of-date. Subclasses overriding this method are supposed to set this value correctly in their call to super.getResourcesToAdd.

Returns:

an array of resources to add for each fileset passed in as well as a flag that indicates whether the archive is uptodate.

Throws:

BuildException - if it likes

Since:

Ant 1.7

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.
