AndFileFilter

public class AndFileFilter extends AbstractFileFilter implements Serializable, ConditionalFileFilter
A {@link java.io.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.
