## Class ForwardOnlyStorageException

- Object
- - Throwable
  - - Exception
    - - DataStoreException
      - - ForwardOnlyStorageException

- All Implemented Interfaces:
    Serializable, LocalizedException

      public class ForwardOnlyStorageException
      extends DataStoreException

  Thrown when an operation would require to move the cursor back, but the underlying storage does not allow that. For example this exception is thrown if the user wants to read the same data a second time, but the underlying ReadableByteChannel is not seekable.

  This exception typically does not depend on the `DataStore` implementation, but rather on the `StorageConnector` value given to the data store.

  Since:
    0.8

    `ReadOnlyStorageException`, Serialized Form

  Defined in the `sis-storage` module
