> Currently the file operations can not return any result after being executed. A simple interface should allow marking the operations that return something without being too strict about what they return.
> I'm working on a command line shell based on VFS that also allows executing operations (http://vfs-utils.sourceforge.net/shell). For the moment I found nothing better than to check for a method getResult() but it I would prefer to just check for the interface.
> The interface could be something like this:
> package org.apache.commons.vfs.operations;
> public interface FileOperationResult {
> 	public abstract Object getResult();
> }
> For me returning a String would be good enough,  but I think returning an Object the most appropriate. In the vfs shell I just do a toString() on it.
