That seems like a really bad way to pass in such a thing.

You really shouldn't use 'FileDescriptor'. Haven't others commented on this to you before?

"The main practical use for a file descriptor is to create a FileInputStream or FileOutputStream to contain it.
Applications should not create their own file descriptors."

So you want to ignore that advice why?

Anyway, to answer your question, you load it into RAM the same way you would any 
'FileInputStream'.

Create one around your 'FileDescriptor' and continue as you should have in the first place 
from the stream.

To put it another way, create the stream first, then pass it into your file handler routine.

 process( new FileInputStream( fileDescriptorIShouldNotHaveUsed ));

and thus

 public void process( InputStream input ) throws IOException { ... }
