      public class AndFileFilter
      extends AbstractFileFilter
      implements ConditionalFileFilter, Serializable

  A `FileFilter` providing conditional AND logic across a list of file filters. This filter returns `true` if all filters in the list return `true`. Otherwise, it returns `false`. Checking of the file filter list stops when the first filter returns `false`.
