Package org.apache.commons.io.filefilter
Class FileFileFilter
java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.FileFileFilter
- All Implemented Interfaces:
FileFilter
,FilenameFilter
,Serializable
,FileVisitor<Path>
,PathMatcher
,PathFilter
,PathVisitor
,IOFileFilter
This filter accepts
File
s that are files (not directories).
For example, here is how to print out a list of the real files within the current directory:
Using Classic IO
File dir = FileUtils.current(); String[] files = dir.list(FileFileFilter.INSTANCE); for (String file : files) { System.out.println(file); }
Using NIO
final Path dir = PathUtils.current(); final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(FileFileFilter.INSTANCE); // // Walk one directory Files.walkFileTree(dir, Collections.emptySet(), 1, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getFileList()); // visitor.getPathCounters().reset(); // // Walk directory tree Files.walkFileTree(dir, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getDirList()); System.out.println(visitor.getFileList());
