Class StaleSequenceException

All Implemented Interfaces:
SilentException, com.hazelcast.spi.impl.operationservice.WrappableException<StaleSequenceException>, Serializable

public class StaleSequenceException extends RuntimeException implements SilentException, com.hazelcast.spi.impl.operationservice.WrappableException<StaleSequenceException>
An RuntimeException that is thrown when accessing an item in the Ringbuffer using a sequence that is smaller than the current head sequence and that the ringbuffer store is disabled. This means that the item isn't available in the ringbuffer and it cannot be loaded from the store either, thus being completely unavailable.

      public StaleSequenceException wrap()
      Description copied from interface: com.hazelcast.spi.impl.operationservice.WrappableException
      Returns a new exception of the same type as this exception, using this exception as its cause. This is useful when this is a remote or async exception, because its stack trace is disconnected from the client code that handles the exception. The returned exception includes all the state of this exception, while providing the local stack trace and the remote/async stack trace in its cause.
      Specified by:
      wrap in interface com.hazelcast.spi.impl.operationservice.WrappableException<StaleSequenceException>
      a new WrappableException with this as its cause.
