Early review on NIO Stream APIs (original) (raw)

BiPredicate is a intentional choice, as during the walk process, the attribute is read and many times, filtering is based on file attributes.

PathMatcher is basically a Predicate, developer can easily use that in a filter with walk, which return a Stream.

Hope that helps.

Cheers, Henry

The find() method uses a

BiPredicate<Path, BasicFileAttributes> matcher what about using the existing java.nio.file.PathMatcher interface? There are already some implementations of PathMatcher both in JDK and in the wild. PathMatcher doesn't accept the file attributes though, but that's a problem for most Path-based APIs - path alone often isn't enough and app has to look up attributes in a separate step.

While lambda still finalizing the final API for Stream, there are a couple of streamifaction APIs in nio area, which I would like to start circling around to get early feedbacks. Those APIs return a CloseableStream, other than that, there is not much directly connection to Stream definition. The specdiff and webrev is available at http://cr.openjdk.java.net/~henryjen/ccc/8006884.0/ Please include me in the reply as I don't necessary receiving emails from all aliases. Cheers, Henry
