Class WildcardFilter

This filter selects files, but not directories, based on one or more wildcards and using case-sensitive comparison.

The wildcard matcher uses the characters '?' and '*' to represent a single or multiple wildcard characters. This is the same as often found on Dos/Unix command lines. The extension check is case-sensitive. See FilenameUtils.wildcardMatch(String, String) for more information.

For example:

Using Classic IO

 File dir = new File(".");
 FileFilter fileFilter = new WildcardFilter("*test*.java~*~");
 File[] files = dir.listFiles(fileFilter);
 for (String file : files) {
     System.out.println(file);
 }
 

Using NIO

 final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(new WildcardFilter("*test*.java~*~"));
 //
 // 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());
