Subject [jira] [Commented] (VFS-255) Allow file operations to return a result
Date Tue, 14 Apr 2015 13:14:13 GMT

    [ https://issues.apache.org/jira/browse/VFS-255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14494097#comment-14494097

Philipp Brügger commented on VFS-255:
-------------------------------------

This feature requires deeper studies of how this can be implemented and offered via the existing
interfaces. I would recommend putting this feature to the future release and schedule it when
the concept is more clear.

>             Project: Commons VFS
>          Issue Type: Improvement
>    Affects Versions: 2.0

> 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.
