Package org.apache.commons.io.filefilter
Class HiddenFileFilter
java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.HiddenFileFilter
- All Implemented Interfaces:
FileFilter,FilenameFilter,Serializable,FileVisitor<Path>,PathMatcher,PathFilter,PathVisitor,IOFileFilter
This filter accepts
Files that are hidden.
Example, showing how to print out a list of the current directory's hidden files:
Using Classic IO
File dir = FileUtils.current();
String[] files = dir.list(HiddenFileFilter.HIDDEN);
for (String file : files) {
System.out.println(file);
}
Example, showing how to print out a list of the current directory's visible (not hidden) files:
File dir = FileUtils.current();
String[] files = dir.list(HiddenFileFilter.VISIBLE);
for (String file : files) {
System.out.println(file);
}
Using NIO
final Path dir = PathUtils.current(); final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(HiddenFileFilter.HIDDEN); // // 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());
Deprecating Serialization
