 * Converts a parameter to a type.

 * @param <T>         the supported Java type convertible to/from a {@code String} format.
 * @param str         The parameter string contents.
 * @param c           the raw type of the object to be converted.
 * @param annotations an array of the annotations associated with the convertible
 *                    parameter instance. E.g. if a string value is to be converted into a method parameter,
 *                    this would be the annotations on that parameter as returned by
 *                    {@link java.lang.reflect.Method#getParameterAnnotations}.
 * @return            the newly created instance of {@code T}.
