I tried to get an iterator with call backs or opendir/readdir put into the JDK back in 1.3.1/1.4 to no avail.  I'd real like to have something as simple as opendir/readdir provided as a stream that is effective and non memory intensive.  I currently have to use JNI to do opendir/readdir, and I need to have a count function that used readdir or an appropriate mechanism to see when certain thresholds are passed.

DirectoryStream is the equivalent of the directory stream that you get 
with opendir/readerdir. Use of "Stream" in the name is bit unfortunate 
now but it pre-dates the Lambda Streams API. Anyway, as Henry pointed 
out, he's got changes coming that allow you get the Stream associated 
with a directory stream, also walk and find methods for file trees.
