4	setNontransactionalRead(nontransactionalRead) Method javax.jdo.Transaction void setNontransactionalRead( boolean nontransactionalRead ) If true, allow persistent instances to be read without a transaction active. If an implementation does not support this option, a JDOUnsupportedOptionException is thrown. Parameters: nontransactionalRead
4	setOptimistic(optimistic) Method javax.jdo.Transaction void setOptimistic( boolean optimistic ) Optimistic transactions do not hold data store locks until commit time. If an implementation does not support this option, a JDOUnsupportedOptionException is thrown. Parameters: optimistic - the value of the Optimistic flag. Since: JDO 1.0
4	getSynchronization() Method javax.jdo.Transaction Synchronization getSynchronization() The user-specified Synchronization instance for this Transaction instance. Returns: the user-specified Synchronization instance. Since: JDO 1.0
4	[ODB1] Chapter 6 - Persistent Objects (...) method. When a transient object becomes persistent during an active transaction, its content is automatically stored in the database when the transaction is committed (unless it is being deleted before commit). An attempt to call makePersistent(...) when there is no active transaction throws
4	getRetainValues() Method javax.jdo.Transaction boolean getRetainValues() If true, at commit time instances retain their field values. Returns: the value of the retainValues property Since: JDO 1.0
4	Constants.PROPERTY_TRANSACTION_ISOLATION_LEVEL_SNAPSHOT Static Field javax.jdo.Constants String PROPERTY_TRANSACTION_ISOLATION_LEVEL_SNAPSHOT "javax.jdo.option.TransactionIsolationLevel.snapshot" Since: JDO 2.2 See Also: PersistenceManagerFactory.supportedOptions()
4	Constants.PROPERTY_TRANSACTION_ISOLATION_LEVEL_READ_UNCOMMITTED Static Field javax.jdo.Constants String PROPERTY_TRANSACTION_ISOLATION_LEVEL_READ_UNCOMMITTED "javax.jdo.option.TransactionIsolationLevel.read-uncommitted" Since: JDO 2.2 See Also: PersistenceManagerFactory.supportedOptions()
4	Constants.PROPERTY_TRANSACTION_ISOLATION_LEVEL_READ_COMMITTED Static Field javax.jdo.Constants String PROPERTY_TRANSACTION_ISOLATION_LEVEL_READ_COMMITTED "javax.jdo.option.TransactionIsolationLevel.read-committed" Since: JDO 2.2 See Also: PersistenceManagerFactory.supportedOptions()
4	Constants.PROPERTY_TRANSACTION_ISOLATION_LEVEL_SERIALIZABLE Static Field javax.jdo.Constants String PROPERTY_TRANSACTION_ISOLATION_LEVEL_SERIALIZABLE "javax.jdo.option.TransactionIsolationLevel.serializable" Since: JDO 2.2 See Also: PersistenceManagerFactory.supportedOptions()
4	Constants.PROPERTY_TRANSACTION_ISOLATION_LEVEL_REPEATABLE_READ Static Field javax.jdo.Constants String PROPERTY_TRANSACTION_ISOLATION_LEVEL_REPEATABLE_READ "javax.jdo.option.TransactionIsolationLevel.repeatable-read" Since: JDO 2.2 See Also: PersistenceManagerFactory.supportedOptions()

Getting Started

ObjectDB is very easy to use. Follow the Getting Started Tutorial and the Quick Tour manual chapter and in minutes you may be able to write and run first Java programs against ObjectDB.

Prior knowledge or experience in database programming (SQL, JDBC, ORM, JPA, etc.) is not required, but some background in using the Java language is essential.
