Class SymbolicLinkFileFilter
- java.lang.Object
-
- org.apache.commons.io.filefilter.AbstractFileFilter
-
- org.apache.commons.io.filefilter.SymbolicLinkFileFilter
-
- All Implemented Interfaces:
- FileFilter, FilenameFilter, Serializable, FileVisitor< Path>, PathFilter, PathVisitor, IOFileFilter
public class SymbolicLinkFileFilter extends AbstractFileFilter implements Serializable
This filter acceptsFile
s that are symbolic links.For example, here is how to print out a list of the real files within the current directory:
Using Classic IO
File dir = new File("."); String[] files = dir.list(SymbolicLinkFileFilter.INSTANCE); for (String file : files) { System.out.println(file); }
Using NIO
final Path dir = Paths.get(""); final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(SymbolicLinkFileFilter.FILE); // // Walk one dir Files.walkFileTree(dir, Collections.emptySet(), 1, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getFileList()); // visitor.getPathCounters().reset(); // // Walk dir tree Files.walkFileTree(dir, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getDirList()); System.out.println(visitor.getFileList());
