camel 2.18.0 file component filter example

Can someone please provide an example of the new file2 filterFile and
filterDirectory usage with simple expression?
We want to process recursively a directory and its subdirectories but only
matching files or directories (and all its subfiles) that have name YYYYMMDD
lower or equal the run moment.

Any example will do...
thanks!

Thanks Claus, we figured out how to do it. To provide an example:

To process files in a directory on a specific time and date, we create with
other routes a file whose body has the content of the message to post. Files
should be named as 2016-12-28__01-00-58__UTC@some.queue

The filterFile=${file:name} &lt; ${date:now:yyyy-MM-dd__HH-mm} will choose
all files ready to process.
Note that we use &lt; instead of more familiar < since we cannot use
directly the symbol.

We then split the filename at the @ symbol and chose the second part [1] to
send the message to with dynamic endpoint.

        <route id="gt.cron.queue" streamCache="true" trace="false">
            <from
uri="file://{{nfs.filecron}}?autoCreate=true&amp;autoCreate=true&amp;delay=10000&amp;move=cron.done&amp;moveFailed=cron.error&amp;filterFile=${file:name}
&lt; ${date:now:yyyy-MM-dd__HH-mm}"/>
            <convertBodyTo type="java.lang.String" charset="UTF-8"/>
            <toD
uri="activemq:queue:${header.CamelFileNameOnly.split('@')[1]}"/>
        </route>

Hi

You can try look in the unit tests of camel-core as there is likely
some unit tests covering this functionality.
