All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

TransactionConflictException

public class RetryTransactionException
extends KVTransactionException

Exception thrown when an attempt to access a KVTransaction results in a conflict or other condition requiring that the transaction be retried.

Note: although it is usually the case, a RetryTransactionException does not necessarily mean that the transaction failed. In some situations (e.g., involving failed network communication) it may not be possible to determine whether a transaction succeeded or not, and this situation is indicated by throwing a RetryTransactionException. Whether and how often such a "false negative" can occur is a function of the KVDatabase implementation being used; ideally, all transactions are idempotent and therefore correct in either case.

Method Details

duplicate

public RetryTransactionException duplicate()

Description copied from class: KVException

Create a duplicate of this exception, with the current thread's stack frames prepended.

This allows the "same" exception to be thrown multiple times from different locations with different outer stack frames. The KVException.clone() method is used to copy this instance.

Overrides:

duplicate in class KVTransactionException

Returns:

duplicate of this exception with the current thread's stack frame context
