ArchiveCommand: Allow to pass options to underlying stream
Current ArchiveCommand design doesn't allow to pass in options to underlying stream implementations. To overcome this, client has to implement custom format implementation (it cannot be derived from the existing one, because the classes are marked as final), and set the options using ThreadLocal, before the method ArchiveOutputStream createArchiveOutputStream(OutputStream s) is get called. This change extends the ArchiveCommand.Format by allowing to pass option map during creation of ArchiveOutputStream. ArchiveCommand is extended correspondingly. That way client can easily pass options to the underlying streams: Map<String, Object> level = ImmutableMap.<String, Object> of( "level", new Integer(9)); new ArchiveCommand(repo) .setFormat("zip") .setFormatOptions(level) .setTree(tree) .setPaths(paths) .setPrefix(prefix) .setOutputStream(sidebandOut) .call(); Change-Id: I1d92a1e5249117487da39d19c7593e4b812ad97a Signed-off-by: David Ostrovsky <david@ostrovsky.org>
