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.
