Member Function Documentation

deinit()

bool Rpl_async_conn_failover_delete_managed::deinit

(

)

Release the udf_metadata service.

Return values

false	Success
true	Failure. service could not be released

delete_managed()

char * Rpl_async_conn_failover_delete_managed::delete_managed ( UDF_INIT *  init_id, UDF_ARGS *  args, char *  result, unsigned long *  length, unsigned char *  is_null, unsigned char *  error  )

static

Deletes managed network configuration details.

Parameters

[in]	init_id	UDF_INIT structure
[in]	args	UDF_ARGS structure containing argument details
[out]	result	error message
[out]	length	error message length
[out]	is_null	if result is null
[in,out]	error	error code

Returns

error message

delete_managed_deinit()

void Rpl_async_conn_failover_delete_managed::delete_managed_deinit ( UDF_INIT *  init_id )

static

Deinitialize variables initialized during init function.

Parameters

[in]

init_id

UDF_INIT structure

delete_managed_init()

bool Rpl_async_conn_failover_delete_managed::delete_managed_init ( UDF_INIT *  init_id, UDF_ARGS *  args, char *  message  )

static

Initialize and verifies UDF's arguments.

Also sets argument and result charset.

Parameters

[in]	init_id	UDF_INIT structure
[in]	args	UDF_ARGS structure containing argument details
[out]	message	error message

Returns

True if error, false otherwise.

init()

bool Rpl_async_conn_failover_delete_managed::init ( )

overridevirtual

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

Implements Udf_service_impl.
