Document

Method for registering a context - should only be used by RepeatOperations implementations to ensure that #getContext() always returns the correct value.

Usage

From source file:org.springframework.batch.repeat.support.RepeatTemplate.java

/**
 * Execute the batch callback until the completion policy decides that we
 * are finished. Wait for the whole batch to finish before returning even if
 * the task executor is asynchronous.//from w ww.j  a v a 2s  .  c o  m
 * 
 * @see org.springframework.batch.repeat.RepeatOperations#iterate(org.springframework.batch.repeat.RepeatCallback)
 */
@Override
public RepeatStatus iterate(RepeatCallback callback) {

    RepeatContext outer = RepeatSynchronizationManager.getContext();

    RepeatStatus result = RepeatStatus.CONTINUABLE;
    try {
        // This works with an asynchronous TaskExecutor: the
        // interceptors have to wait for the child processes.
        result = executeInternal(callback);
    } finally {
        RepeatSynchronizationManager.clear();
        if (outer != null) {
            RepeatSynchronizationManager.register(outer);
        }
    }

    return result;
}
