/**
 * Implementation of the parameter entity type. Instances of this class hold a
 * value in its {@code String} representation, which is converted upon request
 * and provided as a virtual {@link Value}. The returned {@code Value} is for
 * displaying purposes only. To change the value, held by this parameter, one of
 * its {@code setXYValue(XY)} methods has to be used. {@link ValueType}s
 * supported by this parameter are listed below:
 *
 * <ul>
 * <li>{@link ValueType#STRING}</li>
 * <li>{@link ValueType#DATE}</li>
 * <li>{@link ValueType#BOOLEAN}</li>
 * <li>{@link ValueType#BYTE}</li>
 * <li>{@link ValueType#SHORT}</li>
 * <li>{@link ValueType#INTEGER}</li>
 * <li>{@link ValueType#LONG}</li>
 * <li>{@link ValueType#FLOAT}</li>
 * <li>{@link ValueType#DOUBLE}</li>
 * <li>{@link ValueType#FLOAT_COMPLEX}</li>
 * <li>{@link ValueType#DOUBLE_COMPLEX}</li>
