[hibernate-dev] Passing a Scanner instance

Anticipating Ales' work on the optimization between HEM and the micro container ( http://opensource.atlassian.com/projects/hibernate/browse/HHH-4191 ), I've added a way to pass an instance of Scanner to the persistence unit: - an actual instance (recommended) - the class name of the instance to use Use the hibernate.ejb.resource_scanner property name (HibernatePersistence.SCANNER) In our case, the JPA deployer needs to add the following property Map<String, Object> properties = new HashMap<String, Object>(1); properties.put( HibernatePersistence.SCANNER, mcScannerInstance); persistenceProvider.createContainerEntityManagerFactory(persistenceUnitInfo, properties); I've also changed part of the Scanner interface from /** * return all files in the classpath (ie PU visibility) matching one of these file names * if filePatterns is empty, return all files * the use case is really exact file name. */ Set<NamedInputStream> getFilesInClasspath(URL jartoScan, Set<String> filePatterns); to /** * Return all files in the classpath (ie PU visibility) matching one of these file names * if filePatterns is empty, return all files * the use case is really exact file name. * * NOT USED by HEM at the moment. We use exact file search via getResourceAsStream for now. */ Set<NamedInputStream> getFilesInClasspath(Set<String> filePatterns);
