Craig L Russell commented on JDO-678: ------------------------------------- 12.19 Property Management The operation of a PersistenceManager is partly governed by the settings of various properties, which have been documented in earlier sections. These properties are inherited from the PersistenceManagerFactory from which the PersistenceManager was obtained. The properties can be set by methods such as setMultithreaded. Some properties are not standard but are implementation-defined. After creation of the PersistenceManager, these non-standard properties can only be set via the setProperty method. The list of properties that can be accessed is in Appendix K. void setProperty(String name, Object value); Set the property name to the specified value. A12.19-1 [If a vendor-specific property is not recognized, it is silently ignored.] A12.19-2 [If the value for the property is not supported by the implementation, a JDOUserException is thrown.] A12.19-3 [Property names might exactly match the names of the properties in javax.jdo.Constants or might differ in case only.] For example, javax.jdo.Multithreaded is equivalent to JAVAX.JDO.MultiThreaded or javax.jdo.multiTHREADED. A12.19-4 Properties of the transaction associated with a persistence manager can be accessed via the named property in javax.jdo.Constants. For example, the non-transactional read property of the transaction can be accessed via javax.jdo.option.NontransactionalRead.] Map<String, Object> getProperties(); A12.19-5 [Return a map of String, Object with the properties and values currently in effect. The keys in the map exactly match the corresponding names in javax.jdo.Constants.] A12.19-6 [Changing the values in the map will not affect the properties in the PersistenceManager.] Set<String> getSupportedProperties(); A12.19-7 [Return the set of properties supported by this PersistenceManager.] > Ability to set properties on PersistenceManager > ----------------------------------------------- > > Key: JDO-678 > URL: https://issues.apache.org/jira/browse/JDO-678 > Project: JDO > Issue Type: Improvement > Components: api, specification, tck > Affects Versions: JDO 3 (3.0) > Reporter: Andy Jefferson > Assignee: Craig L Russell > Fix For: JDO 3 maintenance release 1 (3.1) > > Attachments: getProperties.patch, jdo-678.patch > > > It would be desirable to be able to set properties on the PersistenceManager, > so as to be able to configure/change behaviour for a PM.
