 * Selector that chooses files based on whether they are signed or not.
 * @since 1.7
public class SignedSelector extends DataType implements FileSelector {
    private IsSigned isSigned = new IsSigned();

     * The signature name to check jarfile for.
     * @param name signature to look for.
    public void setName(String name) {

     * The heart of the matter. This is where the selector gets to decide
     * on the inclusion of a file in a particular fileset.
     * @param basedir not used by this selector
     * @param filename not used by this selector
     * @param file     path to file to be selected
     * @return whether the file should be selected or not
    public boolean isSelected(File basedir, String filename, File file) {
        if (file.isDirectory()) {
            return false; // Quick return: directories cannot be signed
        return isSigned.eval();
