org.apache.jackrabbit.vault.fs.impl.SubPackageFilterArchive

All Implemented Interfaces:

Closeable, AutoCloseable, Archive

public class SubPackageFilterArchive
extends Object
implements Archive

Archive filter that suppresses the sub packages via the normal tree and allows to extract them individually. Note that it doesn't alter the workspace filter, which is not a problem when /etc/packages is never traversed.
