public Class SessionAssociationInterceptor

Implements com.mysql.cj.interceptors.QueryInterceptor.destroy.

Doc from com.mysql.cj.interceptors.QueryInterceptor.destroy.

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

Implements com.mysql.cj.interceptors.QueryInterceptor.executeTopLevelOnly.

Doc from com.mysql.cj.interceptors.QueryInterceptor.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? If an interceptor issues queries using the connection it was created for, and does not return true for this method, it must ensure that it does not cause infinite recursion.

Returns:boolean

true if the driver should ensure that this interceptor is only executed for the top-level "original" query.

Implements com.mysql.cj.interceptors.QueryInterceptor.init.

Doc from com.mysql.cj.interceptors.QueryInterceptor.init.

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().

Parameters

conn:MysqlConnection

the connection for which this interceptor is being created

props:Properties

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:Log

logger

Returns:QueryInterceptor

@Override

Implements com.mysql.cj.interceptors.QueryInterceptor.postProcess.

Doc from com.mysql.cj.interceptors.QueryInterceptor.postProcess.

Called after the given query has been sent to the server for processing. Interceptors are free to inspect the "original" result set, and if a different result set is returned by the interceptor, it is used in place of the "original" result set. This method will be called while the connection-level mutex is held, so it will only be called from one thread at a time.

Parameters

<T>

Resultset object

sql:Supplier<String>

the Supplier for SQL representation of the query

interceptedQuery:Query

the actual Query instance being intercepted

originalResultSet:T

a Resultset created from query execution

serverSession:ServerSession

ServerSession object after the query execution

Returns:T

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

@Override

Implements com.mysql.cj.interceptors.QueryInterceptor.preProcess.

Doc from com.mysql.cj.interceptors.QueryInterceptor.preProcess.

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.

Parameters

<T>

Resultset object

sql:Supplier<String>

the Supplier for SQL representation of the query

interceptedQuery:Query

the actual Query instance being intercepted

Returns:T

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