Examples of org.apache.derby.iapi.sql.conn.LanguageConnectionContext

org.apache.derby.iapi.sql.conn.LanguageConnectionContext
LanguageConnectionContext keeps the result sets, and activations in use by the current connection.
More stable items, like other factories, are accessible through the LanguageConnectionFactory or the LanguageFactory. @see LanguageConnectionFactory @see org.apache.derby.iapi.sql.LanguageFactory
