java.lang.Objectorg.reflections.vfs.Vfs
public abstract class Vfs
a simple virtual file system bridge
use the fromURL(java.net.URL)
to get a Vfs.Dir
and than use Vfs.Dir.getFiles()
to iterate over it's Vfs.File
for example:
Vfs.Dir dir = Vfs.fromURL(url); Iterablefiles = dir.getFiles(); for (Vfs.File file : files) { InputStream is = file.openInputStream(); }
use findFiles(java.util.Collection, com.google.common.base.Predicate)
to get an
iteration of files matching given name predicate over given list of urls
fromURL(java.net.URL)
uses static Vfs.DefaultUrlTypes
to resolves URLs
and it can be plugged in with addDefaultURLTypes(org.reflections.vfs.Vfs.UrlType)
or setDefaultURLTypes(java.util.List)
.
for example:
Vfs.addDefaultURLTypes(new Vfs.UrlType() { public boolean matches(URL url) { return url.getProtocol().equals("http"); } public Vfs.Dir createDir(final URL url) { return new HttpDir(url); //implement this type... (check out a naive implementation on VfsTest) } }); Vfs.Dir dir = Vfs.fromURL(new URL("http://mirrors.ibiblio.org/pub/mirrors/maven2/org/slf4j/slf4j-api/1.5.6/slf4j-api-1.5.6.jar"));
