/**
 * This annotation allows to call a method right after the job has been
 * successfully sent for execution. It is useful to clean up the internal
 * state of the job when it is not immediately needed.
 * <p>
 * This annotation can be applied to methods of {@link ComputeJob} instance only.
 * It is invoked on the caller node after the job has been sent to remote node for execution.
 * <p>
 * Example:
 * <pre name="code" class="java">
 * public class MyGridJob implements ComputeJob {
 *     ...
 *     &#64;ComputeJobAfterSend
 *     public void onJobAfterSend() {
 *          ...
 *     }
 *     ...
 * }
 * </pre>
