24.23 java.io.FilenameFilter (JDK 1.0)

This interface defines the accept() method that must be implemented by any object that filters filenames (i.e., selects a subset of filenames from a list of filenames). There are no standard FilenameFilter classes implemented by Java, but objects that implement this interface are used by the java.awt.FileDialog object, and by the File.list() method. A typical FilenameFilter object might check that the specified File represents a file (not a directory), is readable (and possibly writable as well), and that its name ends with some desired extension.

public abstract interface FilenameFilter {
    // Public Instance Methods
            public abstract boolean accept(File dir, String name);
}

Passed To:

File.list(), FileDialog.setFilenameFilter(), FileDialogPeer.setFilenameFilter()

Returned By:

FileDialog.getFilenameFilter()
