Allow file operations to return a result
----------------------------------------
Key: VFS-255
URL: https://issues.apache.org/jira/browse/VFS-255
Project: Commons VFS
Issue Type: Improvement
Affects Versions: 2.0
Reporter: Frank
Fix For: 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.
