Interface Summary

Interface	Description
Connectable	This interface should be implemented by classes that can establish a database connection.
Database	This interface defines database actions for DBRecord instances.
DBLoadMonitor<R extends DBRecord>	This interface defines a load monitor which is notified about each record loaded from the database
DBPersistent	This class should be implemented by all Objects that are database persistent.
DBRecord	This interface ensures a consistent view to objects that are database persistent.
InsertFactory	This interface defines what makes up an InsertFactory for providing insert-default values.

Class Summary

Class	Description
AbstractDBLoadMonitor<R extends DBRecord>	This is the base class for a custom LoadMonitor.
AbstractDBOCredential	This class extends the Credential object such that it contains the parameters to drive the DBOCompiler.
CollectingDBLoadMonitor<R extends DBRecord>	This class just contains a list that collects the loaded records.
ComposedRecord	This is the superclass for all composed records that are build up with DBObjects.
Credential	This class encapsulates the parameters that are necessary to connect to a database via JDBC.
CredentialHandler	This class builds the Credential object from the parsed data.
CredentialWriter	This class writes the content of a Credential in NDF format.
DBColumnChoice	This class encapsulates a possible value for a particular database column whereas the value is associated with a translated textual description for it.
DBConnectionMap	This map stores database connections and manages their access count based on the accessing thread.
DBConnectionPool	This class implements a pool for JDBC database connections.
DBDate	This is a extension of java.sql.Date which provides useful constructors.
DBLoadTask<C extends ApplicationContext>	This task is used to load records asynchronously from the database.
DBObject	This is the abstract base class for modeling records of a database table as Java Objects.
DBOTypeMapCredential	This class extends a credential such that it also contains the OR-type-mapping
DBPoolConnection	This class wraps a JDBC database connection and adds some functionality to make it maintainable in a ConnectionPool.
DBRecordContainer<R extends DBRecord>	This class encapsulates an inner instance of DBRecord
DBRecordWrapper<R extends DBRecord>	This class is used typically for wrapping a DBObject instance which implements the DBRecord interface and thus can be handled by DBRecordTable, DBRecordList and other DBRecord capable classes.
DBSupport	This class convenience routines for database access
DBTime	This is an extension of Time which automatically fills the non visible time fields to the current datetime values.
DBTimestamp	This is an extension of Timestamp.
DBUtil	Collection of convenience methods that provide support for the DBObjects.
DBUtil.EmptyBlob	Represents an empty Blob object.
DBUtil.EmptyClob	Represents an empty Clob object.
InsertDefaultFactory	This class may provide insert default values for any DBObject field.
LocalDatabase	This class encapsulates the database access done by DBObjects and performs them on a local database connection.
PrimaryKeyFactory	This class serves as a primary key generator for DBObjects.
RecordIterator<R extends DBObject>	This Iterator executes a select query on the given master instance and then iterates through the ResultSet.
ResultData	This is a special TableModel which fills itself from a ResultSet.
SqlCondition	This class allows for constructing SQL conditions in an object oriented manner.
SqlIterator	This Iterator reads the given text and splits it up into a list of SQL statements.
SqlOrder	This class allows for constructing SQL order clause in an object oriented manner.
StatementCache	This cache stores prepared statements of various DBObjects.
TableSkipList	This list defines tables to be skipped during DBObject compilation.

Enum Summary

Enum	Description
DBAction	Defines database actions that can result in an SQLException being thrown
DBChangeType	Defines database actions that result in a change of database data

Exception Summary

Exception	Description
ConnectionNotAvailableException	This Exception is thrown when a pool-connection is not available immediately of after a specified amount of time.
ConnectionNotEstablishedException	This Exception is thrown by a DBObject when any database action is requested but a database connection has not yet been established.
ConnNeverTakenException	This Exception is thrown when a thread tries to return a connection he has never taken before.
DataConversionException	Is thrown when a sting cannot be converted to the given class type
InsertFailedException	This Exception is thrown when an INSERT of a DBObject record fails
InvalidPrimaryKeyException	This Exception is thrown by DBRecords if an UPDATE or REHASH is tried with an invalid primary key.
NoCurrentRecordException	This Exception is thrown when an action is being performed on a current record, but the current record is nost set
NoMatchingRecordFoundException	This exception it thrown when a parent record expects to find sub-records, but none has been found.
NotInTransactionException	This Exception is thrown when COMMIT or ROLLBACK was called by a thread who is not running in a transaction
RecordNotFoundException	This exception is thrown if the given record could not be found in the database.
ShuttingDownException	This Exception is thrown when a pool-connection is requested by a client during shutdown.
TooManyRecordsFoundException	This exception it thrown when a parent record expects exactly a single sub-record, but many sub-records have been found.

Package de.esprit.appsuite.database.dbase Description

Contains most of the database related classes. The most important class here is BObject which is used to model database records as Java objects. There is a set of automatically generated DBObject subclasses in the dbo package, one for either table in the database.
