024 * <p>
025 * Checks that class type parameter names conform to a format specified
026 * by the format property.  The format is a

028 * <strong>^[A-Z]$</strong>.
029 * </p>
030 * <p>
031 * An example of how to configure the check is:
032 * </p>
033 * <pre>
034 * &lt;module name="MethodTypeParameterName"/&gt;
035 * </pre>
036 * <p>
037 * An example of how to configure the check for names that are only a single
038 * letter is
039 * </p>
040 * <pre>
041 * &lt;module name="MethodTypeParameterName"&gt;
042 *    &lt;property name="format" value="^[a-zA-Z]$"/&gt;
