    027 * <p>
    028 * A specialized parameter class for configuring {@code PropertiesConfiguration} instances.
    029 * </p>
    030 * <p>
    031 * This class allows setting of some properties specific to properties configuration, for example the layout object. By
    032 * inheriting from {@link FileBasedBuilderParametersImpl}, basic properties and properties related to file-based
    033 * configurations are available, too.
    034 * </p>
    035 * <p>
    036 * This class is not thread-safe. It is intended that an instance is constructed and initialized by a single thread
    037 * during configuration of a {@code ConfigurationBuilder}.
    038 * </p>
