void |
destroy()
Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed. |
boolean |
executeTopLevelOnly()
Should the driver execute this interceptor only for the "original" top-level query, and not put it in the execution path for queries that may be executed from other interceptors? |

void |
init(Connection conn,
java.util.Properties props)
Called once per connection that wants to use the interceptor The properties are the same ones passed in in the URL or arguments to Driver.connect() or DriverManager.getConnection(). |

postProcess(java.lang.String sql,

Called after the given statement has been sent to the server for processing, instead of the StatementAware postProcess() of the earlier api. |

conn
- the connection for which this interceptor is being createdprops
- configuration values as passed to the connection. Note that
in order to support javax.sql.DataSources, configuration properties specific
to an interceptor must be passed via setURL() on the
DataSource. StatementInterceptor properties are not exposed via
accessor/mutator methods on DataSources.
java.sql.SQLException
- should be thrown if the the StatementInterceptor
can not initialize itself.public ResultSetInternalMethods postProcess(java.lang.String sql, Statement interceptedStatement, ResultSetInternalMethods originalResultSet, Connection connection, int warningCount, boolean noIndexUsed, boolean noGoodIndexUsed, java.sql.SQLException statementException) throws java.sql.SQLException
