Methods

public static BaseQuery<T>

createDefaultQueryObject(Class ifc, DataSource ds) throws SQLException Details

Creates a concrete implementation of a Query interface using the Java SE QueryObjectGenerator implementation.

ifc The Query interface that will be created

ds The DataSource that will be used when invoking methods that accesss the data source. The QueryObjectGenerator implementation will use this DataSource without any unwrapping or modications to create connections to the data source.

return A concrete implementation of a Query interface

Throws SQLException: if a database access error occurs.

public static BaseQuery<T>

createDefaultQueryObject(Class ifc, Connection con) throws SQLException Details

Creates a concrete implementation of a Query interface using the Java SE QueryObjectGenerator implementation.

ifc The Query interface that will be created

con The Connection that will be used when invoking methods that accesss the data source. The QueryObjectGenerator implementation will use this Connection without any unwrapping or modications to create statements from the data source.

return A concrete implementation of a Query interface

Throws SQLException: if a database access error occurs.

public static BaseQuery<T>

createQueryObject(Class ifc, DataSource ds) throws SQLException Details

Creates a concrete implementation of a Query interface using the JDBC driver's QueryObjectGenerator implementation. This method will attempt to invoke DataSource.createQueryObject() and if the method does not exist on the DataSource, createDefaultQueryObject will be invoked to create the concrete implementation of a Query interface.

ifc The Query interface that will be created

ds The DataSource that will be used when invoking methods that access the data source. The QueryObjectGenerator implementation will use this DataSource without any unwrapping or modications to create connections to the data source.

return A concrete implementation of a Query interface

Throws SQLException: if a database access error occurs.

createQueryObject(Class ifc, Connection con) throws SQLException Details

Creates a concrete implementation of a Query interface using the JDBC driver's QueryObjectGenerator implementation. This method will attempt to invoke Connection.createQueryObject() and if the method does not exist on the Connection, createDefaultQueryObject will be invoked to create the concrete implementation of a Query interface.

ifc The Query interface that will be created

con The Connection that will be used when invoking methods that access the data source. The QueryObjectGenerator implementation will use this Connection without any unwrapping or modications to create statements from the data source.
