Member Function Documentation

deinit()

bool Udf_service_impl::deinit

(

void

)

Release the mysql_service_mysql_udf_metadata service and unregisters the Asynchronous Connection Failover's UDFs.

Return values

true	if there was an error
false	if all UDFs were unregistered

init()

virtual bool Udf_service_impl::init ( )

pure virtual

Initialize variables, acquires the mysql_service_mysql_udf_metadata from the registry service and register the Asynchronous Connection Failover's UDFs.

If there is an error registering any UDF, all installed UDFs are unregistered.

Return values

true	if there was an error
false	if all UDFs were registered

Implemented in Rpl_async_conn_failover_add_managed, Rpl_async_conn_failover_add_source, Rpl_async_conn_failover_delete_managed, Rpl_async_conn_failover_delete_source, and Rpl_async_conn_failover_reset.

register_udf()

bool Udf_service_impl::register_udf

(

Udf_data &

e

)

Registers the Asynchronous Connection Failover's UDFs.

If there is an error registering any UDF, all installed UDFs are unregistered.

Return values

true	if there was an error
false	if all UDFs were registered

set_registry()

void Udf_service_impl::set_registry ( const mysql_service_registry_t *  r )

inline

Save UDF registry service.

param[in] r UDF registry service.

unregister_udf()

bool Udf_service_impl::unregister_udf

(

const std::string

udf_name

)

Unregisters the Asynchronous Connection Failover's UDFs.

Return values

true	if there was an error
false	if all UDFs were unregistered
