 * <h2>Usage Example</h2>
 *
 * <pre>
 * {@code

 * </pre>

When submitting code, please make every effort to follow existing conventions
and style in order to keep the code as readable as possible. Please also make
sure your code compiles by running `./gradlew check`. Checkstyle failures
during compilation indicate errors in your style and can be viewed in the

     * In Maven 3, when a resource configuration specifies:
     * </p>
     * <pre>{@code
     * <resource>
     *   <directory>src/main/resources</directory>
     *   <targetPath>META-INF/resources</targetPath>
     * </resource>
     * }</pre>
     * <p>
     * The maven-resources-plugin resolves {@code targetPath} as:

 *
 * <pre>
 * import static org.codelibs.core.beans.util.CopyOptionsUtil.*;
 *
 * copyBeanToBean(srcBean, destBean, excludeNull());
 * </pre>
 * <p>
 * The return value of {@literal CopyOptionsUtil} is {@link CopyOptions},
 * so you can specify multiple options using method chaining.

 * FILE_WRITE_DATA</code>) and the target file has the following security
 * descriptor ACEs:
 *
 * <pre>
 * Allow WNET\alice     0x001200A9  Direct
 * Allow Administrators 0x001F01FF  Inherited
 * Allow SYSTEM         0x001F01FF  Inherited
 * </pre>
 *
 * the access check would fail because the direct ACE has an access mask
 * of <code>0x001200A9</code> which doesn't have the

   * to stop requests. You could poll for lifecycle changes in a work loop:
   *
   * <pre>
   *   public void run() {
   *     while ({@link #isRunning()}) {
   *       // perform a unit of work
   *     }
   *   }
   * </pre>
   *
   * <p>...or you could respond to stop requests by implementing {@link #triggerShutdown()}, which
   * should cause {@link #run()} to return.

 * <p>Note that only top-level classes with either a non-private constructor or a non-private static
 * factory method to construct instances can have their instance methods checked. For example:
