Example 26 with IOFileFilter

use of org.apache.commons.io.filefilter.IOFileFilter in project applause by applause.

the class FileUtils method listFiles.

/**
 * Finds files within a given directory (and optionally its
 * subdirectories). All files found are filtered by an IOFileFilter.
 * <p>
 * If your search should recurse into subdirectories you can pass in
 * an IOFileFilter for directories. You don't need to bind a
 * DirectoryFileFilter (via logical AND) to this filter. This method does
 * that for you.
 * <p>
 * An example: If you want to search through all directories called
 * "temp" you pass in <code>FileFilterUtils.NameFileFilter("temp")</code>
 * <p>
 * Another common usage of this method is find files in a directory
 * tree but ignoring the directories generated CVS. You can simply pass
 * in <code>FileFilterUtils.makeCVSAware(null)</code>.
 *
 * @param directory  the directory to search in
 * @param fileFilter  filter to apply when finding files.
 * @param dirFilter  optional filter to apply when finding subdirectories.
 * If this parameter is <code>null</code>, subdirectories will not be included in the
 * search. Use TrueFileFilter.INSTANCE to match all directories.
 * @return an collection of java.io.File with the matching files
 * @see org.apache.commons.io.filefilter.FileFilterUtils
 * @see org.apache.commons.io.filefilter.NameFileFilter
