Examples of com.mysql.clusterj.ClusterJException

com.mysql.clusterj.ClusterJException
ClusterJException is the base for all ClusterJ exceptions. Applications can catch ClusterJException to be notified of all ClusterJ reported issues.
Exceptions are in three general categories: User exceptions, Datastore exceptions, and Internal exceptions.
- User exceptions are caused by user error, for example providing a connect string that refers to an unavailable host or port.
  - If a user exception is detected during bootstrapping (acquiring a SessionFactory), it is thrown as a fatal exception. {@link ClusterJFatalUserException}
  - If an exception is detected during initialization of a persistent interface, for example annotating a column that doesn't exist in the mapped table, it is reported as a user exception. {@link ClusterJUserException}
- Datastore exceptions report conditions that result from datastore operations after bootstrapping. For example, duplicate keys on insert, or record does not exist on delete. {@link ClusterJDatastoreException}
- Internal exceptions report conditions that are caused by errors in implementation. These exceptions should be reported as bugs. {@link ClusterJFatalInternalException}
