[jboss-as7-dev] VFS question and how to extract contents of deployment root

[Scott Marlow]

It looks like VirtualFile.getPhysicalFile() uses the FileSystem API. 
How does the FileSystem.getFile() compare to the 
MountHandle.getMountSource()?

Javadoc from VirtualFile.getPhysicalFile:

"
Get a physical file for this virtual file.  Depending on the underlying 
file system type, this may simply return an already-existing file; it 
may create a copy of a file; or it may reuse a preexisting copy of the 
file.  Furthermore, the retured file may or may not have any 
relationship to other files from the same or any other virtual directory.

@return the physical file
"

MountHandle.getMountSource() javadoc:

"Get the source file used for the mount.
"
