  org.springframework.batch.retry.support.RetrySynchronizationManager

public class RetrySynchronizationManager
extends Object

Global variable support for retry clients. Normally it is not necessary for clients to be aware of the surrounding environment because a RetryCallback can always use the context it is passed by the enclosing RetryOperations. But occasionally it might be helpful to have lower level access to the ongoing RetryContext so we provide a global accessor here. The mutator methods (clear() and register(RetryContext) should not be used except internally by RetryOperations implementations.
