https://jira.jboss.org/jira/browse/SHRINKWRAP-104 I've added support for empty directories (and tests) in r3836. This is nice, because importers can now account for empty dirs as well. The design I've used is a new Asset implementation: public enum DirectoryAsset implements Asset { | | /** | * Singleton Instance | */ | INSTANCE; | | /** | * {@inheritDoc} | * @see org.jboss.shrinkwrap.api.Asset#openStream() | */ | @Override | public InputStream openStream() | { | // To signify that we've got nothing to back us (we're just a directory), | // we use null. A stream backed by an empty byte array would be an | // empty file, which is different. | return null; | } | | } This sucks because: 1) We don't really obey the contract of "Asset", returning a null reference on "openStream" 2) The implementation relies upon "instanceof" runtime type checking to do things like creating directories in the exporter. Meaning we're checking for a specific implementation. An alternate approach is to add: Asset.isDirectory() ...to all Asset types. In this case "DirectoryAsset.openStream" would still return null, but we could do "Asset.isDirectory" instead of the runtime type checking. Which is uglier to you?
