Method Detail

preProcess

public <T extends Resultset> T preProcess(java.util.function.Supplier<java.lang.String> sql,
                                          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:

sql - 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.

preProcess

public <M extends Message> M preProcess(M queryPacket)

Description copied from interface: QueryInterceptor

Called before the given query packet is going to be sent to the server for processing. Interceptors are free to return a PacketPayload, and if so, the server will not execute the query, and the given PacketPayload 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.

Type Parameters:

M - Message object

Parameters:

queryPacket - original Message

Returns:

processed Message

postProcess

public <T extends Resultset> T postProcess(java.util.function.Supplier<java.lang.String> sql,
                                           Query interceptedQuery,
                                           T originalResultSet,
                                           ServerSession serverSession)

Description copied from interface: QueryInterceptor

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.

Specified by:

postProcess in interface QueryInterceptor

Overrides:

postProcess in class BaseQueryInterceptor

Type Parameters:

T - Resultset object

Parameters:

sql - the Supplier for SQL representation of the query

interceptedQuery - the actual Query instance being intercepted

originalResultSet - a Resultset created from query execution

serverSession - ServerSession object after the query execution

Returns:

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