Help with org.jivesoftware.openfire.filetransfer package

The FileTransferInterceptor interface as described allows to capture information about the file transfer before it begins . I would like to know whether it is possible to store the bytes(file) sent between clients through openfire server?

Say the org.jivesoftware.openfire.filetransfer.FileTransfer class has a method getProgress() which inturn returns an instance of class org.jivesoftware.openfire.filetransfer.FileTransferProgress

This class(FileTransferProgress) has two methods, getInputStream() and getOutputStream()

Is it possible to read the data sent through the server using the InputStream or the OutputStream?
