public enum Isolation
Enumeration that represents transaction isolation levels for use with the JDK 1.5+ transaction annotation, corresponding to the TransactionDefinition interface.

|---|---|
| DEFAULTUse the default isolation level of the underlying datastore. | |
| READ_COMMITTEDA constant indicating that dirty reads are prevented; non-repeatable reads and phantom reads can occur. | |
| READ_UNCOMMITTEDA constant indicating that dirty reads, non-repeatable reads and phantom reads can occur. | |
| REPEATABLE_READA constant indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur. | |
| SERIALIZABLEA constant indicating that dirty reads, non-repeatable reads and phantom reads are prevented. | |
