Method Detail

getMetadata

public void getMetadata(MetadataFactory metadataFactory,
               Connection conn)
                 throws TranslatorException

Description copied from class: ExecutionFactory

Implement to provide metadata to the metadata for use by the engine. This is the primary method of creating metadata for dynamic VDBs.

Overrides:

getMetadata in class ExecutionFactory<DataSource,Connection>

Throws:

TranslatorException

createProcedureExecution

public ProcedureExecution createProcedureExecution(Call command,
                                          ExecutionContext executionContext,
                                          RuntimeMetadata metadata,
                                          Connection connection)
                                            throws TranslatorException

Overrides:

createProcedureExecution in class ExecutionFactory<DataSource,Connection>

Throws:

TranslatorException

getConnection

public Connection getConnection(DataSource ds)
                         throws TranslatorException

Description copied from class: ExecutionFactory

Return a connection object from the given connection factory. The default implementation assumes a JCA ConnectionFactory. Subclasses should override, if they use another type of connection factory.

Overrides:

getConnection in class ExecutionFactory<DataSource,Connection>

Returns:

a connection

Throws:

TranslatorException

closeConnection

public void closeConnection(Connection connection,
                   DataSource factory)

Description copied from class: ExecutionFactory

Closes a connection object from the given connection factory. The default implementation assumes a JCA Connection. Subclasses should override, if they use another type of connection.

Overrides:

closeConnection in class ExecutionFactory<DataSource,Connection>
