026/**
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>
039 *
040 * @since 2.0
