Method Detail

init

public QueryInterceptor init(MysqlConnection conn,
                             java.util.Properties props,
                             Log log)

Description copied from interface: QueryInterceptor

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().

Specified by:

init in interface QueryInterceptor

Overrides:

init in class BaseQueryInterceptor

Parameters:

conn - the connection for which this interceptor is being created

props - 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. QueryInterceptor properties are not exposed via accessor/mutator methods on DataSources.

log - logger

Returns:

QueryInterceptor

destroy

public void destroy()

Description copied from interface: QueryInterceptor

Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed.

Specified by:

destroy in interface QueryInterceptor

Overrides:

destroy in class BaseQueryInterceptor

preProcess

public <T extends Resultset> T preProcess(java.util.function.Supplier<java.lang.String> str,
                                          Query interceptedQuery)

Description copied from interface: QueryInterceptor

Called before the given query is going to be sent to the server for processing. Interceptors are free to return a result set (which must implement the interface Resultset), and if so, the server will not execute the query, and the given result set will be returned to the application instead. This method will be called while the connection-level mutex is held, so it will only be called from one thread at a time.

Specified by:

preProcess in interface QueryInterceptor

Overrides:

preProcess in class BaseQueryInterceptor

Type Parameters:

T - Resultset object

Parameters:

str - the Supplier for SQL representation of the query

interceptedQuery - the actual Query instance being intercepted

Returns:

a Resultset that should be returned to the application instead of results that are created from actual execution of the intercepted query.
