Persistence layer implementation.

See: Description

Interface Summary

Interface	Description
CommitTxRunnable	A Runnable that gets invoked before a physical commit.
ConnectionManager	Connection Manager for local connections. JDBC connections are never used directly.
IdSource	Source of ID numbers.
IdSourceConfigurator	Configurator for an IdSource.
ModificationLogFactory	The ModificationLog factory.
RemoteSessionFactory	Factory for remote sessions.
RollbackTxRunnable	A Runnable that gets invoked before a physical rollback.

Class Summary

Class	Description
AbstractDbObject<P extends AbstractDbObject<P>>	A persistent low-level database object.
AbstractDbOperation<P extends AbstractDbOperation<P>>	A AbstractDbOperation provides methods that are not part of AbstractDbObjects and is associated to a Db-session.
AbstractIdSource	Base implementation for IdSources.
Db	A logical database connection.
DbDiagnosticUtilities	Utilities for diagnostic purposes with persistence extensions.
DbFactory	Session factory for Db instances.
DbModification	Modification information per table.
DbObjectClassVariables<P extends AbstractDbObject<P>>	Holds static class variables for classes derived from DbObject.
DbObjectClassVariables.ForeignReference
DbOperationClassVariables<P extends AbstractDbOperation<P>>	Holds static class variables for classes derived from AbstractDbOperation.
DbPreferences	Database backend for the Preferences API. Tentackle preferences are stored in a database rather than a file(unix) or registry(windows).
DbPreferencesFactory	Implementation of a PersistedPreferencesFactory.
DbPreferencesKey	A preferences key/value pair stored in the database.
DbPreferencesNode	Preferences Node stored in the database.
DbRemoteSessionFactory	Default implementation for a remote session factory.
DbTransaction	Holder for transaction local data.
DbTransactionHandle	A unique handle to reference an object within a DbTransaction.
DefaultConnectionManager	The default implementation of a connection manager. Each Db will get its own physical connection.
DefaultDbPool	An implementation of a database pool. It allows min/max sizes, fixed increments and timeouts for unused instances.
DefaultIdSourceConfigurator	Default IdSourceConfigurator.
DefaultModificationLogFactory	Default implementation of a modification log factory.
IdComparator<P extends AbstractDbObject<?>>	Compares the object ids of two AbstractDbObjects.
IgnoreDuplicatesPersistenceVisitor	A visitor to ignore duplicates within a persistence operation. Used to avoid duplicate key errors (for example in AbstractPersistentObject.insertPlainWithComponents()), if components are referenced more than once within the same root entity.
ManagedConnection	A jdbc connection managed by the ConnectionManager. The connection provides some additional features such as a prepared statement cache and translates SQLExceptions to DbRuntimeExceptions.
MasterSerial	Holds the master serial and optional application-specific data.
ModificationLog	Logging for object modifications. Modifications to AbstractDbObjects can be logged to a so-called modification log (aka: modlog). Most applications will use the modlog for asynchroneous database coupling.
ModificationLog.ReplayState	Replay state shared between consecutive invocations of ModificationLog.replay(org.tentackle.persist.ModificationLog, org.tentackle.persist.Db).
ModificationTally	Counter to track modifications for a class/table. The ModificationTracker maintains a list of ModificationTally-objects, one for each tracked name.
ModificationTracker	The modification tracker for the tentackle persistence layer.
MpxConnectionManager	Multiplexing connection manager. A connection manager for applications with a large number of Db instances, e.g.
NameComparator<T extends AbstractDbObject<?>>	Compares the string representation (toString()) of two AbstractDbObjects.
NameIdComparator<T extends AbstractDbObject<?>>	Compares the names + IDs of two AbstractDbObjects.
ObjectId	An IdSource to create unique object IDs.
ObjectSequenceId	An IdSource to create unique object IDs from a database sequence.
PersistenceVisitor	A reflective visitor to add application-specific functionality to persistence operations.
PreparedStatementWrapper	A wrapper for prepared statements. Will catch and report SQLExceptions and keep track of being used only once after Db.getPreparedStatement(org.tentackle.persist.StatementKey, boolean, int, int, java.util.function.Supplier<java.lang.String>).
Query	A database query.
RemoteSessionAdapter	Adapter for a remote session. Hides the RMI stuff.
ResultSetCursor<T extends PersistentDomainObject<T>>	A cursor for a ResultSetWrapper.
ResultSetCursor.FetchList<T>	Adds a closed flag to saveObject a roundtrip in remote sessions.
ResultSetSection	A section of columns within the result set.
ResultSetSkipBlock	A subset of the columns returned by a ResultSetWrapper.
ResultSetWrapper	A wrapper for ResultSets.
StatementHistory	History of statement execution.
StatementId	A statement id.
StatementKey	The statement key.
StatementStatistics	Statement statistics collector.
StatementWrapper	A wrapper for sql statements. Will catch and report SQLExceptions and keep track of being used only once after Db.createStatement().
TableSerialExpirationBacklog	Keeps a backlog of expiration sets. Used in RMI-servers to reduce database roundtrips for clients requesting the expiration info for their local caches.

Exception Summary

Exception	Description
IdSourceEmptyException	Runtime exception thrown if an idsource becomes empty.
IdSourceException	Runtime exception thrown for id source failures.
