[classname]#SQLContainer# -is the class implementing the Vaadin [classname]#Container# interfaces and -providing access to most of the functionality of this add-on. The standard -Vaadin [classname]#Property# and [classname]#Item# interfaces have been -implementd as the [classname]#ColumnProperty# and [classname]#RowItem# classes. -Item IDs are represented by [classname]#RowId# and [classname]#TemporaryRowId# -classes. The [classname]#RowId# class is built based on the primary key columns -of the connected database table or query result. - -In the [package]#connection# package, the [classname]#JDBCConnectionPool# -interface defines the requirements for a connection pool implementation. Two -implementations of this interface are provided: -[classname]#SimpleJDBCConnectionPool# provides a simple yet very usable -implementation to pool and access JDBC connections. -[classname]#J2EEConnectionPool# provides means to access J2EE DataSources. - -The [package]#query# package contains the [classname]#QueryDelegate# interface, -which defines everything the SQLContainer needs to enable reading and writing -data to and from a database. As discussed earlier, two implementations of this -interface are provided: [classname]#TableQuery# for automatic read-write support -for a database table, and [classname]#FreeformQuery# for customizing the query, -sorting, filtering and writing; this is done by implementing relevant methods of -the [classname]#FreeformStatementDelegate# interface. - -The [package]#query# package also contains [classname]#Filter# and -[classname]#OrderBy# classes which have been written to provide an alternative -to the standard Vaadin container filtering and make sorting non-String -properties a bit more user friendly. - -Finally, the [package]#generator# package contains a [classname]#SQLGenerator# -interface, which defines the kind of queries that are required by the -[classname]#TableQuery# class. The provided implementations include support for -HSQLDB, MySQL, PostgreSQL ( [classname]#DefaultSQLGenerator#), Oracle ( -[classname]#OracleGenerator#) and Microsoft SQL Server ( -[classname]#MSSQLGenerator#). A new or modified implementations may be provided -to gain compatibility with older versions or other database servers. - -For further details, please refer to the SQLContainer API documentation. - - - |
