By default the transferred file will carry the same name as the original file. If you want to override this behavior you
can set <code>local-filename-generator-expression</code> attribute which allows you to provide SpEL Expression to generate
the name of the local file. Unlike outbound gateways and adapters where the root object of the SpEL Evaluation Context
is <classname>Message</classname>, Inbound adapter generates <classname>Message</classname> based on the transferred file
which means that <classname>Message</classname> does not exist yet at the time of Expression evaluation. So the root object
of the SpEL Evaluation Context is the original name of the remote file (String)

Some times file filtering based on the simple pattern specified via <code>filename-pattern</code> attribute might not be
sufficient. If this is the case, you can use the <code>filename-regex</code> attribute to specify a Regular Expression
