Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?
I'm curious at what Ralph thinks. You could consider providing a PR to add the feature to make the class pluggable and see how much code that touches...

Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?
Greetings, Yes, I was talking about javax.activation.DataSource, which seems to be consistent with what you are doing, but it does not seem to have available in Android i think, so it could be an issue, also same for FileTypeMap, thanks for the clarification.

Hi Carl, WRT DataSource, this is a JDBC interface, which does not seem appropriate for a file system. Or do you mean javax.activation.DataSource. Apache Commons VFS was started a long time ago and not adapted to newer JREs in this area (obviously.)

Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?
Greetings, Thanks for your quick reply! Yes, you are correct. I would like to have a way to change the provider, I would subclass the implementation that you have and use that as content and contentInfo provider. Otherwise, if its not the case, currently i need to reimplement everything, right?

Hi Carl, Do you mean org.apache.commons.vfs2.impl.DefaultFileContentInfo and org.apache.commons.vfs2.impl.FileContentInfo? Ralph, do have issue as to make this pluggable?

[VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?
Greetings, I am interested in using the VFS library for one of my projects, as it has almost everything I need, but i have some questions on it though. My use case is as follows:* For the local file system, I use DESCRIPT.ION files to store attributes of files and directories, so I would need to override some methods of DefaultFileInfo() , mainly all the attribute related functions. How can I set my own FileInfo provider? I did not find any API in the interfaces to do this, maybe, i missed something. * The same is true of FileContent, how can I set my own FileContentInfo provider in FileContent ? I would probably use a feature of JDK 1.6 (the FileTypeMap class) to override the default implementation. Finally an unrelated question, why you do not use the DataSource interface in FileObject available in JDK 1.6, is it because of Android compatibility issues? Thanks in advance for your help,Carl
