[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-275) support NIOFSDirectory and others as optimized FSDirectory extensions

[ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-275?pag... ] Hardy Ferentschik commented on HSEARCH-275: ------------------------------------------- It is not a pure documentation issue (at least not anymore). As of Lucene 3.0 {{FSDirectory.open}} will never return a {{MMapDirectory}}. You will have to instantiate this directory yourself. As mentioned before {{NIOFSDiretory}} is already the default on non Windows systems: {code:title=FSDirectory.java|borderStyle=solid} ... if (Constants.WINDOWS) { return new SimpleFSDirectory(path, lockFactory); } else { return new NIOFSDirectory(path, lockFactory); } ... {code} where {{Constants.WINDOWS}} is the system property _os.name_. I guess one can override the _os.name_ property on the command line when starting the JVM to get an {{NIOFSDirectory}} on Windows. However, this is really a hack and maybe other parts of the app depend on the property as well. The best solution is to either provide additional options in our configuration to be able to control which subclass of {{FSDirectory}} to instantiate or to just add {{NIOFSDirectoryProvider}} and {{MMapDirectoryProvider}} implementations. I prefer the latter since we have already so many configuration options and having explicit provider classes seems clearer. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
