28   * A specialized parameter class for configuring {@code PropertiesConfiguration} instances.

31   * This class allows setting of some properties specific to properties configuration, for example the layout object. By
32   * inheriting from {@link FileBasedBuilderParametersImpl}, basic properties and properties related to file-based
33   * configurations are available, too.

37   * during configuration of a {@code ConfigurationBuilder}.
