 * Converts String to the target type.

 * @param type  actual type definition.
 * @param value string representation of the value which is converted to {@code T}.
 *              In case it is {@code null}, converter should return either {@code null} or a value
 *              that is equivalent e.g. an empty list.
 * @return value converted to type {@code T}.
 * @param attributes additional meta-data attributes which may be used by converter. It can be {@code null}.
 * @throws IllegalArgumentException when {@code value} cannot be converted to {@code T}.
