FileSystem exists

Hi to all,

in my job I have to check if a directory exists and currently I have to
write:

Path myDir = new Path(...);
boolean exists = FileSystem.get(myDir.toUri()).exists(myDir);

Is there a better way to achieve this?

Best,
Flavio

Ok..I don't like to repeat twice myDir but for the moment I can live with
it ;)

Thanks,
Flavio

You can also do "myDir.getFileSystem().exists(myDir)", but I don't think
there is a shorter way...
